Silent Steppe Cantata: Serendipitous transport, to places of unexpected illumination & healing

Silent Steppe Cantata
M   usic can—and often does—transport us to places that no other artform can.”
  —  Anne LeBaron.
T   his international project presents fresh ideas by opening new and often unexpected horizons of creativity. The serious nature and deep content and design of the cantata aroused genuine interest from the public. The Cantata is one of the most important international events of contemporary classical music in Central Asia.”
  —  Aigul Beisenova, Business Kazakhstan.
T here are artistic projects that heal and redeem and enlighten. And then, to our even greater delight, there are those that achieve this across vast cultural and political chasms, auguring well for world peace.



A nne LeBaron’s Silent Steppe Cantata receives its world première today (10-DEC-2011) at the Palace of Peace and Reconciliation in Astana, Kazakhstan.

T he Silent Steppe Cantata Project is an artistic consortium, consisting of composer Anne LeBaron with her co-producer, tenor Timur Bekbosunov, plus filmmaker, Sandra Powers. The multi-media cantata is a sonic and visual portrait of Kazakhstan. Together with Bekbosunov, the Sary-Arka Folk Instrument Orchestra and the Chamber Choir of the Astana Philharmonic Society will perform the official premiere.

Silent Steppe Cantata
T he libretto incorporates Kazakh stories and mythology, and draws upon poems of Russian and Kazakh writers, including the poet Olzhas Suleimenov. Suleimenov has authored more than 16 volumes of poetry and prose, and his 1975 novel Az-i-Ia received both wide recognition in Kazakhstan and abroad, plus censure by Soviet authorities.

Silent Steppe Cantata
T he Palace of Peace and Reconciliation is a 77m high pyramid-shaped facility designed by Foster+Partners Architects and built by Sembol Construction at a cost of 8.74B Kazakh tenge (about USD$58M). Among other things, it houses a 1,500-seat concert/opera hall. It opened in late 2006. What a fitting venue for today’s première!

L istening to excerpts online, I am intrigued by the exposition of Kazakh ethnogenesis that the cantata and film portray. Without being revisionistic or grinding any particular philosophical “axes,” the cantata (the music, and the historical and contemporary texts comprising the libretto) reveals the inherently slippery, shifting imagination of Kazakh ethnic origins. It is their shifting, not a Western shifting; it is an indigenous acceptance of transitoriness/ephemerality that may derive from the primordial “geography” of the Kazakh nation and tribes. Acceptance without relativism/fatalism/determinism.

T he cantata demonstrates evidence of local elders and a musicoliterary elite struggling through the millennia to come to terms with the evolving political demarcations of Central Asia. Through their struggle, they created a handful of discrete ‘nationalities’, sustained through the centuries. If anything, the impression (from the bits of the cantata and film that we can experience online) is one of the indomitability of the spirit and of authentic human diversity. Needless adversity and suffering destroy things; they are never ‘noble’ or ‘desirable.’ But there is this residue of survivors—people, and music, and stories, and culture—and this once-dogged, now-expansive persistence of the will to peace. This cantata inspires as well as teaches!

W ish we could be there for the première!

The Darwin Project: Does a Multimedia Biography Need to Have a ‘Center’?

Charles Darwin
A   loose-jointed affair that never really found an aesthetic center.”
  — Robert Trussell, Kansas City Star, 15-OCT-2011.
W hen I read Robert Trussell’s review, I thought about how different mindsets and expectations can produce profoundly different experiences for different attendees at a performance. Trussell came to the Friends of Chamber Music premiere of The Darwin Project event with one set of expectations, geared to his commitment to write a review to be published in a daily newspaper on deadline. I came to the event with a different set of expectations--with only a genuine interest, really; that is, with no specific objective or purpose. (I attend lots of events; I only write about some of them, mostly ones that are strictly chamber music per se. This event was theatrical and multimedia, and I only decided to write this blogpost after seeing what Trussell wrote. I feel that Trussell’s words do not reflect what I and others who attended experienced, and that is what prompted me to post about it.)

T hree actors (Gary Neal Johnson, Darwin and others; Kathleen Warfel, Emma Wedgwood (Darwin’s wife) and others; Cinnamon Schultz, narrator) portrayed Charles Darwin’s life story (script by Jeremy M. Lillig and Nancy Cervetti), accompanied by classical music performed by the Daedalus String Quartet, solo pianist Alon Goldstein, and Kansas City Collegium Vocale chamber choir, under the direction of Ryan Board. Above the performers on-stage, historical images and dramatic original nature photography were projected on a large, suspended screen—animations, montages, and stills.

T he musical performances were impeccable throughout. Direction by Kyle Hatley was insightful and dynamic. The actors—especially Gary Neal Johnson—fully inhabited their characters. The imagery was well-chosen to complement and synchronize with the dramatic arc and cadences of the music. The sound reinforcement (which Trussell complained about) was just fine for those of us who were down in the Orchestra section. (Not sure where Trussell was seated Friday night, but it should be recognized that it has only been a few weeks since the Kauffman Center opened, and the people manning the mixing console up in the studio loft are surely still just discovering as they go what the optimal level settings are for various ensemble types, genres, miking configs, and audience sizes.) The staging and deployment of the musicians and actors were thoughtful. The lighting direction was done in a manner that appropriately emphasized the shifts in action and mood. The antiques/props, complete with rare blooming orchids and fossils, lent just the right amount of atmosphere.

T he one issue about which Trussell and I agree is the bit about the small percentage of the audience clapping after each ‘number’. It is vital that—for productions that are comprised of multiple short segments or ‘scenes’, and where piddling, confused applause will disrupt the atmosphere and continuity of the performance—the presenter should instruct the audience before the program begins: ‘Please do not applaud until the end.’ Simple.

B ut, gee, look at what this thing is! And look, too, at the fact that this was its premiere performance! The writing of lives is inherently difficult and complex, and The Darwin Project should, I think, be considered on its merits as biography. The aims of accuracy and commemoration can undoubtedly be helped by multimedia content, to convey what is hard to capture in words. Well-chosen music and images can clarify and intensify the characterization of the multiple milieux that affected the person the biography is about, over a long (73-year) and illustrious lifetime. The agnostic and Unitarian and Anglican excursions in Darwin’s changing (‘evolving’?) religious/spiritual thought, were elegantly and empathetically suggested by the diversity of the music selected for The Darwin Project:
  • Anonymous - Antiphon for the Feast Day of St. Albert, Patron Saint of Science
  • Mendelssohn - String Quartet No. 2, Op. 13, adagio, allegro vivace
  • Debussy - Preludes, Book 2, ‘Canope’
  • Schumann - Fantasiestücke, Op.12, ‘Des Abends’
  • Schumann - Fantasiestücke, Op.12, ‘Aufschwung’
  • Byrd - Mass for 5 voices, ‘Gloria’
  • Ravel - Miroirs ‘Une Barque sur l’oceane’
  • Haydn - String Quartet in C major, Op. 33, No. 3, allegro moderato
  • Chopin - Prelude in B-flat major, Op. 28, No. 21
  • Debussy - Preludes, Book 2, ‘Les tierces alternées’
  • Des Prez - Inviolata
  • Chopin - Prelude in A major, Op. 28, No. 7
  • Janácek - 1.X.1905 Sonata ‘Smrt’
  • Mendelssohn - String Quartet No. 6 in F minor, Op. 80, allegro vivace assai
  • Vaughan Williams – ‘See the Chariot at Hand’ (cantata from ‘In Windsor Forest’)
N o. Despite the fame of ‘Origin of Species’ and the reductionistic way in which modern popular society regards who he was and what he did, Darwin did not have just one lifelong aesthetic or ideological ‘center’, and it would be wrong for a biography of him to portray him as if he did. Lillig’s and Cervetti’s quotations and adaptations of Darwin’s writings amount to a kind of verbal portraiture—well-paced; at times humorous; a fine antidote to the monolithic ‘evolutionist-naturist’ caricature that exists of him in popular society. The music likewise opposes one-dimensional caricatures of the man. The production informs the viewers-listeners and invites the audience to think and reflect and imagine and feel and understand and apply, as any good biography should do.

I n fact, the matter of opposing claims and methods of science versus the imagination are a recurring issue in modern discussions of biographical methods. Serious biographers usually agree that their conclusions, while grounded in facts and a scholarly, scientific process of sifting and evaluating evidence, are at bottom ‘intuitive’ in much the way that medical diagnosis is ‘intuitive’: the biographer perceives meaning and reaches conclusions in a high-dimensionality, time-varying set of data; the biographer reliably finds patterns and takes decisions in the face of extreme complexity and contradictions and counter-factuals.

T   he facts of his life become the most interesting—and perhaps the most ‘true’—just at the edge of mystery.”
  — Jay Martin, commenting about the process of writing the biography of Henry Miller.
R eading all the the extant materials, being open to all points of view on the subject of the biography—these are just prologue to the biographer’s purpose, which is to intuit accurately what it all means and express that in a convincing and authentic way to others, even if the story is irreducibly complex and the intuitions do not reveal just one ‘center’. The Darwin Project succeeds beautifully as multimedia biography of a very remarkable, complex person.

P .S.—You may especially like the Hamilton and Rollyson books (links below).

P .P.S.—Lee Hartman's arrangement (for SATB and string quartet) of Vaughan Williams’s ‘See the Chariot at Hand’ was superb... warm, very moving with end-of-life atmospherics, beautiful orchestration, and a balanced and emotionally-fitting concluding work for this production. Bravo!

¡Sacabuche! Matteo Ricci: His Map and Music

Sacabuche, IU Jacobs School of Music
J   ust as western countries have never heard the teaching of the sages of China, so we Chinese have never heard of the books of their ancient sages. Both now enlighten each other; both benefit one another.”
  — Feng Yingjing, acquaintance of Fr. Matteo Ricci, 16th-Century China.
S acabuche! is an ensemble of Chinese and western instruments and voices directed by Linda Pearse. Sacabuche! performed a series of concerts and workshops in Beijing, China, in December, 2010, and yesterday at BEMF in Boston offered a multimedia performance of their work about the Italian Jesuit priest (and mathematician, scientist, cartographer, and all-around polymath), Matteo Ricci, whose decades spent in China in the late 16th century resulted in the first map in Chinese. Ricci’s detailed map, completed and presented to the Wanli Emperor in 1602, showed the entire world—eastern and western hemispheres—surprising and edifying both the Chinese and the Italians.

I U Jacobs School of Music faculty members Stanley Ritchie and Wendy Gillespie contributed to the collaboration, as did University of Minnesota professor of History, Ann Waltner. The performance combined historical readings with early music from both sixteenth- and seventeenth-century Europe and China, along with new compositions by Oberlin/Juilliard-trained now-New-York-based composer Huang Ruo, commissioned for the Sacabuche! project.

T he multimedia performance reanimates the seminal political and cultural exchange between Italian Jesuits and Chinese literati in 16th/17th-century China and unifies (1) Italian music of Ricci’s Italy performed on period instruments, (2) Chinese music of Ricci’s China performed on traditional Chinese instruments, (3) Huang Ruo’s new music, (4) dramatic readings, and (5) historical imagery, including a projected digitized version of Ricci’s map (an old original, James Ford Bell Library, U of M) Chinese paintings and calligraphy and other artworks.
  • Linda Pearse, artistic director & sackbut
  • Ann Waltner, co-director, speaker, author of program notes/script
  • Qin Fang, speaker
  • Yang Yi, guzheng
  • Carrie Tsujui Chin, sheng
  • Eunji Lee, piano and organ
  • Sarah Barbash-Riley, Ray Horton & François Godère, sackbut
  • Martie Perry & Janelle Davis, Baroque violin
  • Wendy Gillespie, viola da gamba
  • Elise Figa, soprano
  • Andrew Rader, countertenor
  • Benjamin Geier, tenor
  • Huang Ruo, composer
  • Cathy Barbash, producer
T he thoughtful selection of 16th-Century Chinese imagery alternating with Italian Baroque Catholic Church imagery was accompanied by short descriptive and poetical Chinese and English texts read by Qin Fang and by Ann Waltner, respectively, interleaved with the Chinese and Italian Baroque music. The pace and the variety of sonic textures were really exciting—informing those of us who do not know very much about Chinese or Jesuit history; capturing and holding our interest throughout; and inspiring our expanding wonder about what the decades-long contact that Fr. Ricci and his Chinese hosts had with each other really entailed.

H uang Ruo’s “Fisherman’s Sonnet” is patterned after kun opera but includes a number of exotic orchestrations of Chinese and western instruments that have probably never been heard playing together before (sackbuts! viola da gamba! Baroque organ! with sheng and guzheng!).

C arrie Tsujui Chin’s sheng playing and Yang Yi’s guzheng were masterful and incisive—at times forcefully and at other times poignantly and delicately contrasting with the rest of the ensemble’s Baroque Italian harmonies.
  • Huang Ruo – Fisherman’s Sonnet
  • A. Gabrieli – Benedictus Dominus Deus Sabaoth
  • A. Gabrieli – Ricercar
  • A. Gabrieli – Alla Battaglia
  • Anon. – Tianfeng huanpei (Jade Pendants of the Immortals)
  • G. Palestrina – Quan pulchri Sunt
  • G. Nanino – Amor m’ha posto; I pensier so saette
  • G. Palestrina – Nigra sum, sed formosa
  • Bartolomeo de Selma – Vestiva i colli
  • G. Palestrina – Vestiva i colli
  • Anon. – Gaoshan liushui (Lofty Mountains and Rolling Waters)
  • A. Gabrieli – Ricercar arioso
  • G. Palestrina – Surgam et circuibo civitatem
  • Huang Ruo – My Promises are Above
Qin Fang, IU Jacobs School of MusicT he readings were graceful and passionately delivered. Some of the readings are excerpts from Ricci’s diaries and letters—poetical in their own way and manifesting not so much the worldview of a missionary of the Roman Catholic Church as the personal and good-hearted expressions of a human being who is deeply and continually interested in other people and how they live, continually interested in learning, and in Life. Over his 30+ years in China, Ricci was fluent in writing and speaking Chinese and came to be highly regarded by the local Chinese scholars with whom he came into contact.

R   icci [Li Xitai] … there is not a single one of our books that he has not read… In a noisy gathering of several dozen people with everybody speaking at once, the arguments he is following do not disturb him at all… [Other people] err through an excess of either inflexibility or compliancy… they are all inferior to him.”
  — Li Zhi, letter to a friend regarding Ricci, 1600.
I f one totes up the durations of the various segments of the performance, the Chinese texts and music occupy considerably less time than the Baroque western music and Ricci texts. This is, after all, a production about Ricci and his activity and travels and his map. But the Chinese material is not merely ‘context’ or ‘backdrop’ for the Ricci saga; it is aesthetically and expressively as strong as the rest. The guzheng and sheng music is, if anything, revealing of a greater depth of existential reflection and contemplation on the part of the Chinese—of a great intellectual openness and spiritual preparedness to receive whatever insights a new experience [with Ricci, or with others] might offer—contrasted with the still-transcendent-but-more-constrained conceptions of Gabrieli or Palestrina. From the performance, we get the strong message that the illustrious Chinese Ricci encountered and whose writings survive were extraordinary human beings, every bit as much as Ricci was extraordinary.

T here are, naturally, other, less sanguine perspectives on Ricci and his accomplishments (see some of the books linked below). Indeed, some of Huang Ruo’s music conveys the diversity of Chinese opinion about the Jesuit(s) in their midst. Ricci’s chronic reluctance to forthrightly state what his or the Church’s purposes and intentions were in China evidently wore thin at times—graciousness has its limits, and there has to be an acceptable bilateral flow of value, or convincing and ongoing prospects of future value flow, for the relationship/exchange/intrusion to be sustainable. Huang Ruo’s music and the ensemble’s playing provide a balanced and empathetic, speculative account of this cross-cultural give-and-take. This is not surface-level alternating now-Chinese-now-Western-sacred-music collage or ‘documentary’; instead, the dramatic tension of the work derives from the fact that the sequence of compositions does recreate this diversity, this give-and-take, complete with the politics and misapprehensions in it. Not inscrutable! Quite the opposite.

M any thanks to the IU and U of M for producing and performing this beautiful and exciting work! International Relations par excellence!

Kari Johnson & Robert Burke: ‘Unity’ Concert

Robert BurkeM any things to be enthused about last night, regarding Kari Johnson’s and Robert Burke’s KCeMA performance at Unity Temple.
  • Christopher Biggs – The Ends of Histories (piano, electronics, and video, 10-min)
  • Peter Swendsen – Nothing that is not there and the Nothing that is (instrumented bass drum and electronics, 8.5-min)
  • Jeff Herriott – Velvet Sink (piano and electronics, 13-min)
  • João Pedro Oliveira – Liquid Bars (vibraphone and electronics, 12-min)
  • Scott Blasco – Queen of Heaven (piano and electronics, 23-min)
C hristopher Biggs’s ‘The Ends of Histories’ for piano, digital video and audio represents ideas regarding how history must end—any history, all Histories—including religious ones, socio‐political ones, geological histories, all of them. A primary-color-heavy, apocalyptic video of watery scenes and splotches of color is displayed on a screen adjacent to pianist Kari Johnson. The high-contrast, posterized quality of the video’s color palette adds to the non-human, bichromatic wolf-vision, Terminator-vision, Predator-vision, insect-vision viewpoint of the camera/cameraperson. The piano part is full of sforzando emphases, a hyper-percussive quality that is meant to mate with the punctate, unforgiving synth and cosmically abject waveform-samples on the digital audio tracks. Ms. Johnson provided a spirited, empathetic reading, flawless.

T   he materials represent the following conceptions of the end of history: (1) a polarized religious End Time whereby everyone either ascends into a Pleasant World or descends into Fire—a prophetic, spiritual, transcendent End that has appeared in many forms throughout history and is currently represented by the idea that there will be some kind of cataclysm at the end of the Mayan calendar in 2012; (2) a sociopolitical End in which capitalist democracy supplants all other ideologies...; and (3) ‘scientific’ Ends... mass-extinctions.”
  — Christopher Biggs, composer.
P eter Swendsen’s ‘Nothing is not there and the Nothing that is’ for miked/instrumented bass drum and electronics draws its inspiration from violent forces of wind and weather. Forces of Nature are the architects of the sonic space and textures, and humans are compulsory respondents to natural events that are not of their choosing. The majority of the piece consists of canticle-like ‘verse-and-responsory’ segments, each about one minute in length. The human percussionist (Robert Burke) is entrained in Nature’s mesh (electronics, plus waveforms captured by mics—his own playing, digitally processed, delayed, pitch-bent, filtered, and replayed through monitors adjacent to him on-stage). The piece is written in such a way that the performer becomes progressively more mindful of the sonic consequences of each gesture, each mallet stroke, for what the future will become—and we in the audience experience this sense of the long-term impact that we have, on each other, on other species, and on the planet as a whole. Burke’s finesse with extended mallet techniques—including inducing aeroelastic drum-head vibrations with his hypothenar eminence and including wiping a stick fitted with a red silastic scrubber on the drum-head to evoke wild-animal growls and anguished roaring—were ‘Never-heard-anything-like-that-before!’ breathtaking.

A   long the coast, this collision is a constant negotiation: the land and sea changing back and forth; the clouds that hover near the shoreline. In the interior, however, wind and weather do not negotiate.”
  — Peter Swendsen, composer.
J oão Pedro Oliveira’s ‘Liquid Bars’ delivers sonic textures that marry live marimba/vibraphone with the electronically-processed signals from two large dynamic ribbon mics positioned at approximately mid-resonator-tube height on the left side and right side of the instrument. The electronically-processed sounds mutate spontaneously under software control, modulated by the mallet strikes. The increasingly complex polyphonies and polyrhythms are fascinating and unnerving—almost like interviewing a person whose acute psychiatric problems have landed the person in your Emergency Room in the wee hours of a Saturday night. The notion of ‘self’ is called into question, not only who the self or ‘selves’ are—the one(s) in front of you—but also whether the whole assumption that ‘who’ any of us are is stable and ascertainable is faulty. The composition has ketamine-like psychotropic properties. Gee, should FDA and DEA regulate this music as a Schedule II pharmaceutical? Powerful! Robert Burke’s 4-mallet technique is superb...

Vibraphone
L   et us imagine a Marimba who can produce sound... Let us imagine that the Performer and the Marimba would each have the possibility of dividing themselves into two or more instruments and performers—and imagine that all of these play against each other.”
  — João Pedro Oliveira, composer.
J eff Herriott’s ‘Velvet Sink’ is a piece that explores the possibilities of the piano through both extended performance techniques and the use of digital audio. I worry that technical obsolescence tends to make works like these short-lived. Several works realized on the IRCAM’s realtime audio processor 4X, for example, can no longer be performed, because the equipment and operating-system become obsolete so fast and cannot readily be ‘refactored’ and ported to new configurations that can render the same effects as the old ones. There are maintenance problems even with well-structured software. Pieces for ‘tape’ survive: the process of recording will always be ported to more recent technologies, such as CDs, DVDs, and hard disks. Here, though, Herriott’s Max/MSP scripts and Peak and ProTools elements are fairly portable and are likely to withstand the technology changes of this decade and the next. Kari Johnson gives tactile, delicate treatments of the keyboard passages. Repetitive eighth-note patterns, very insistent, have undulating up-down microtonal bends applied to them, until the patterns feel like waves, a gentle-swell aquatic envelope—the sonic surface is a kind of ‘minimalism-built-out-of-complexity’, sort of oxymoronic jumbo-shrimp. Then she stands up, reaches into the piano and begins plucking strings with fingertips and fingernails; hammering piano strings with percussion mallets; modifying the placements of rubber erasers between strings, prepared-piano-style—at times music-box-like, at times chime-like.

Kari Johnson
S   amples were recorded using both a baby grand and an out-of-tune piano-harp from a destroyed upright piano. Some of these sound snippets were then processed and patched to generate longer sound files that were, in turn, reconfigured with ProTools. Others, notably the plucked gestures in the third movement, sound in performance much as they did during the recording. Ultimately, a unique Max/MSP patch is used in performance to control the playback of the recorded material.”
  — Jeff Herriott, composer.
S cott Blasco’s (b'79) Queen of Heaven, composed for Ms. Johnson and premiered last night, consists of five movements, each conceived as [a religious—] icon, concerning itself with a single idea, turning it over and over, meditating on it from different angles. ‘Queen of Heaven’ is dedicated to the Blessed Virgin Mary, “a source of comfort and inspiration to Christians from the earliest years of their history,” in the composer’s words. Blasco’s composition, informed by his Master’s degree in Theology from Fuller Theological Seminary and degree in Composition and Music Theory from Calvin College, is a highly personal exegesis. The angels’ ‘greeting’ the Mother of God in the first movement conveys more of a confrontation—as in Awed and Struck Dumb—than a ‘greeting’. Sonority and terror appear linked in other of the movements as well, enough to cause most to have second-thoughts about the appeal of the Pearly Gates.
W   hen I write music, I’m not writing it ‘for me’ per se. I see it as holding out an olive branch to my audience, and offering praise by mirroring the Creator.”
  — Scott Blasco, composer.
K ari Johnson is a DMA student at UMKC Conservatory where she studies with John McIntyre. She holds bachelor’s degrees in Piano Performance and Piano Pedagogy from the University of Central Missouri, a master’s degree in Piano Performance from Bowling Green State University, and a master’s degree in Piano Pedagogy from the University of Illinois Urbana-Champaign. Ms. Johnson has won or placed in competitions throughout the Midwest, including the MTNA Steinway Young Artist Competitions in Missouri and Illinois and the Venetia Hall Concerto Competition. An active performer of new music and chamber music, Ms. Johnson’s recent performances include collaborative concerts at the University of Central Missouri and Pittsburg State University, UMKC’s “Carter and Messiaen at 100” festival, and the CMS Great Plains Chapter 2009 Regional Conference. In the coming year she will perform at the 2010 UCM New Music Festival and the 2010 SEAMUS National Conference.

R obert Burke is also a DMA student at UMKC Conservatory. He has enjoyed an eclectic carrier performing, studying and teaching throughout Canada, The United States, Japan and Europe. He is originally from Alberta, Canada although for the last decade has hailed New Orleans as home. A strong advocate of new music, Mr. Burke has commissioned and performed countless solo percussion works in recital and held member ship in New Works Calgary, Syncronia (St. Louis) and Conundrum New Music Ensemble. He has also been a regular member of the Edmonton Symphony Orchestra, The Calgary Philharmonic and The Louisianna Philharmonic. As a drumset player, Mr. Burke has performed and toured with a remarkable number of recording artists in clubs and festivals throughout the United States and Europe, including Brian Lee, Johnny Sansone, Preston Hubbard, Frankie Ford, Cyril Neville, Allen Toussaint, Irma Thomas, Peter Nero, Marvin Hamlish, and Robert Goulet. He holds degrees from University of Alberta and the University of Calgary and has served on the faculty of the University of Calgary, Mount Royal College, the University of Missouri-Columbia and Central Methodist College.

Burtner’s ‘A’aa’, Grace Lai, flute, and Michael Abrams, clarinet

Grace Lai (flute) & Michael Abrams (clarinet) perform Matthew Burtner’s ‘A’aa’ at KcEMA event at La Esquina in Kansas City (03-DEC-2010)

H    ow much information is carried in [neural] spike trains? Should we use the discrete theory or the continuous one? Spike times are not discrete, and discrete calculations don’t seem to give satisfactory answers. But, on the other hand, the continuous theory assumes a continuous space, and, from the available evidence, that is clearly too strong an assumption to be valid. What, then, is the [mathematical, topological, metric] space to which spike train phenomena belong? While it might be possible to define the sum of two spike trains by simple linear superposition, it isn’t at all obvious how to define the difference. There is no reason to expect spike trains to be Euclidean. For example, with regard to color perception, MacAdam ellipses in color space are wildly non-Euclidean.”
  —  Conor Houghton, Trinity College, Dublin.
T he acoustic and optic stimuli we received at the KcEMA event held last night at La Esquina in Kansas City were intense, sensorially immersive, emotionally evocative, and thoroughly satisfying in terms of their well-crafted dramatic arcs, accessibility, and comprehensibility. The seven works performed were selected from among 120 compositions that were submitted by composers from around the world, in response to KcEMA’s call-for-scores last Spring.
  1. Elainie Lillios (composer), Bonnie Mitchell (visual artist) – “2BTextures”: 2-movement work of abstract animation “takes the audience on an integrated sonic and visual journey into a surrealistic environment influenced by Nature.” This is an edgy, edgy piece with extensive, dramatic use of surround-sound spatial movement of sound, around the Mackie speaker array that was deployed around the perimeter of the audience seating area. The computer-generated visual displays were very high-dimensionality animations, with many tens of thousands of dynamic objects projected in motion at each moment.
  2. Bret Battey (composer, videographer) – “Sinus Aestum”: inspired by the eponymous plain on the Moon’s surface, smooth and dark, “articulated by threads of white dust, like the tips of flowing waves.” Music and video sequences are propelled by algorithmic processes that sample the digital imagery of surface topographic XYZ structures of this lunar plain. It reminds me of ‘Swarm’ software, with autopoiesis and phase-transitions generated by adaptive networks of communicating processes, much like nonlinear reaction-diffusion equations in statistical physics and chemistry, such as the Belousov-Zhabotinsky reaction and other processes in non-equilibrium thermodynamics. Composer as Dawkinsonian “blind watch-maker” impersonal God, initializing the universe and letting Creation auto-unfold as it may. This is utterly phenomenal and without doubt one of the most elegant unifications of light and music I have so far had the pleasure to experience. Bravo!
  3. Matthew Burtner (composer) – “A’aa”: includes field recordings of lava flows and associated sounds emitted by an active Guatemalan volcano, and expresses deep ecology at a primeval, violent, chaotic, low frequency-spectrum, butt-thumping level via the Mackie SRS1500 subwoofer—convincingly conveying the notion that human affairs are puny compared to stochastic geophysical mechanical processes: not only beyond our control but largely beyond the reach of human technologies even to monitor or measure or predict. Burtner’s Nature is uncaring; however, it is not malevolent. It does not wreak shock and awe on all sentient life-forms, human and otherwise. Instead, the shrieks and rumblings of the Earth pushing viscous molten rock are surprisingly benign; nothing is imminently about to explode; this Guatemalan volcano is somewhat like standing very close to a powerful waterfall that is not going anywhere and is not going to kill us. The lava cools, creating solid crusts, and these smash together under the pressure of still-molten material behind them, generating breaking, shattering sounds. [I very much liked the percussionist, mashing fist-sized lava rocks together. The miked grating, smacking sounds of these added high-frequency effects on top of the thundering volcano sounds. Grace Lai’s flute and Michael Abrams’s clarinet, both playing long, sustained notes with pitch-bending and harmonics rounded out this ecoexperience, complementing the timbres of the realtime volcano sounds.]
  4. Jeffrey Hass (composer), Elizabeth Shea (choreography) – “Magnetic Resonance Music”: composed after his having an MRI exam, during which he “focused on bizarre, strident, extremely loud noises and complex rhythms the machine was making.” The world according to Hass has humans as guinea pigs, to whom things are done or happen passively while doctor-priests tell you to hold perfectly still. Shea’s choreographed movements are wonderful counterparts to Hass’s impulsive quasi-chaos syncopated music. Very cool!
  5. Christopher Burns (composer) – “Sawtooth”: mash-up of elements of visual performance and sound-art. Instead of a personal sensor-area network with transducers capturing biomechanics signals from a live performer’s limbs and trunk (3-axis accelerometers, gyros, joint goniometer angles, etc.), Burns uses the video camera on the LCD monitor of his laptop computer to capture the motions of his arms and torso and hands, which he moves Theremin-style . Scene-recognition, edge-detection, and vector velocity computations from the realtime video image datastream of motions of the performer captured from the camera are translated in software and converted into both music and visual animation. The gestures are transformed into a rich palette of pitch set and crescendo/decrescendo and articulation and other motifs. Simultaneously, the gestures yield an interesting range of optical and animation effects, projected on the walls of the performance space. The spatial positions and colors and intensities and sizes (scale) where newly ‘launched’ animation objects appear depend on the position and speed and direction as well as ‘open-hand/closed-hand’ morphology of gestures that Burns makes with his hands. The result is a truly beautiful, cohesive integration of sound and light. [Just as with the recent ‘Faster Than Sound’ event at Aldeburgh, there are issues regarding our less-than-optimal notational idioms for scoring complex computer/electronic music – video/light-show compositions, to sufficiently specify what comes precisely when and specify interfaces for multiple disparate acoustic and optical effects in technology-interoperable, manufacturer-independent ways – so as to facilitate future rehearsals and performances by persons other than the composer/video artist/dancer(s) and on the equipments of future decades when the computers and other devices and patches we now have are long-since obsolete.]
  6. Robert Ratcliffe (composer) – “Phoenix”: repeated resurrection from sonic ashes “explores the possibility of combining characteristic features of synthetic‐driven electronic dance music genres such as acid house and techno” with elements of instrumental and electroacoustic composition. I am reminded of the sounds that titanium robot insects make during the raves that precede their exuberant mating season. This thing is absolutely danceable—very, very nice.
  7. Mike McFerron (composer) – “Prelude to You Brought This On Yourself”: sonically explores the physical and emotional abuse experienced by an openly homosexual youth, and “attempts to comment on a human collective intolerant of an individual voice, who is not asking to be understood or even heard, but simply allowed to exist.” The tintinnabulations of small bells are synchronized with images of people that flash in front of us, accompanied by short voice-over recordings, mostly of anti-gay hate-speech by conservative religious figures. This is a deeply moving, powerful testament to the courage and resilience of those who are harmed—be prepared to be moved to tears as you listen and watch: no mere electronic music or multimedia installation work, it is a galvanizing, effective example of art as political intervention to bring about a more just society.

Battey – ‘Sinus Aestum’

Battey—‘Sinus Aestum’

W hy do light shows combined with music affect us in ways that are substantially different from either stimulus taken separately? Are there features of dynamic light displays that, when designed and synchronized with music, might optimally stimulate our senses and enhance the depth of our reception of the music?

I s there a point of “sensory overload” or “diminishing returns” as regards multi-sensory stimulation to accompany music? Conversely, why do periods of silence or darkness that sometimes arise in electronic music / lightshow events cause hallucinatory acoustic and optical experiences? How might composers understand and leverage these neurophysiologic phenomena to better advantage, expressively?

M ight there in the future be implantable prosthetic devices—or legal, safe, and effective “performance-enhancing medications” (esp. glutamatergic ones or GABA-ergic ones, to modulate corticofugal transmission)—that could further enhance or extend the scope of these tandem multi-sensory experiences?

W hen I fly on long trans-oceanic flights and listen to my iPod, my perceptions of music are distorted, sometimes in interesting, revelatory ways. How, if at all, would combinations of music and light in zero-gravity space environments differ? Could space-tourism include specially-composed music and accompanying light displays that would capitalize on the sensory biophysics anomalies up there, to produce an extraordinary kind of transcendence for the travelers?

M ight electroacoustic music-light compositions in the future be composed so as to be more effective for music therapy purposes, compared to current conventional “music-only” music therapy?

H ow do the experiences that people with autism-spectrum disorders have of light-sound compositions differ from others’ experiences?

T hese questions occurred to me last night as I listened to the performances of electroacoustic and computer-based compositions at La Esquina in Kansas City. (The same questions had dogged me when I attended last month’s ‘Faster Than Sound’ event in Snape.)

Christopher Burns performs ‘Sawtooth’

Burns – ‘Sawtooth’

N eural coding has traditionally been assumed to be one of rate-coding: the stronger the stimulus, the more action-potentials per second that a sensory neuron transmits, and the stronger the perceived sensation is.

H owever, it’s now known that in various sensory systems there is ‘sparse temporal neural coding’. The timing and univariate temporal pattern of action-potentials and sequences of clusters of them in a single neuron itself carries information. The bivariate or multivariate temporal pattern of concurrently-incident action-potentials in multiple neurons, which may perhaps be in different sensory pathways (such as acoustic nerve and optic nerve pathways, thalamic pathways, cortical pathways, etc.) may likewise carry [different] information.

T he processing of sensory information by the brain is difficult to understand, in part because of complex interconnections between the sub-cortical and cortical areas. connections between the thalamus and the cortex in the brain are reciprocal, with information carried both in “feed-forward” [peripheral nerves to thalamus to cortex] and “feed-back” [cortex to thalamus] directions. Sensory signals reach the cerebral cortex after having traversed many synapses along multiple pathways. Acoustic and optical signals interact in the thalamus and possibly elsewhere, in both mutally excitatory and mutually inhibitory ways.

C onor Houghton at Trinity College, Dublin, has recently examined spectro-temporal receptive fields and filter functions in studies of the neurophysiology of bird song, using analytic formalisms of van Rossum metrics and non-Euclidean spaces. Useful, I think, for human music analysis, and not just of multi-sensory music-visual works...

A nd Stephen Coombes’s and Paul Bressloff’s edited volume (link below) covers how the patterns of spiking activity provide a substrate for the encoding and transmission of information, that is, how do neurons compute with spikes? It is likely that an important element of both the dynamical and computational properties of neurons is that they can exhibit bursting, which is a relatively slow rhythmic alternation between an active phase of rapid spiking and a quiescent phase without spiking—which is altered by “cross-talk” (statistical cross-correlations) between the spiking patterns evoked by concurrent stimulation by music and light.

Belousov-Zhabotinsky reaction
W ith regard to the ‘sensory overload’ question, there is a fair amount of recent research that is germane to this. In mathematics, the triangle inequality is a defining property of norms and measures of distance. This property must be established as a theorem for any function proposed for such purposes for each particular space. For example, the triangle inequality holds for spaces such as the real numbers, Euclidean spaces, Lp spaces (p ≥ 1), and inner-product spaces. Maybe it also holds for multidimensional perceptual spaces, such as ones involving simultaneous stimulation by sound and light.

E ven if these are one-of-a-kind experiences never to be quite the same twice, and even if the communication impact of multisensory stimulation is subadditive in terms of quantitative neurophysiology and biophysics, the qualitative expressive and aesthetic result of any particular performance can nonetheless be really, really wonderful. Congratulations to each of these composers/artists/performers on these fine compositions and ‘sensorially whelming’ performances at KcEMA!

M    usical Ecoacoustics embeds environmental systems into musical and performance structures using new technologies. Ecoacoustics derives its musical procedures from abstracted environmental processes, remapping data from the ecological into musical domain. It draws on techniques of sonification, acoustic ecology and soundscape composition (e.g, Truax, Westerkamp, Keller and others). The data from nature may be audio information (from wind or ocean waves, for example), or it may be a signal produced from some measurable parameter such as temperature timeseries, geological change or seismic data, astrophysical data, and so on. Going beyond mere direct sonification, the composer develops a syntax on the basis of the recorded natural processes, and creates new patterns conforming to this syntax.”
