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.

Sound Art: Beyond Mere Music

 Christopher Biggs; Rebecca Ashe
Interactive Gestures, a performance of electroacoustic music and multimedia works, with guest artist João Pedro Paiva de Oliveira, was held last night at La Esquina, in Kansas City, co-sponsored by the American Institute of Architects (AIA) and by the UMKC Conservatory. One could say that it was a healing of the wound between ‘fixed-media’ and ‘live’ electroacoustic performance. The unity of the aesthetic effect of the musicians who performed live and the composers who engineered their fixed-media playback was among the best I’ve ever heard.

Composers who create works for fixed-media (recorded and edited in the studio; replayed in performance halls) are maybe more comfortable in the studio than on-stage. For them, performance is in the studio, but probably not more so than for traditional composers. The spatialization that’s achieved in concert may be subject to many environmental variables and interpretive choices that are out of the composer’s control, just as any chamber or orchestral work is out of the composer’s control at the moment of performance. Last night, as in other electroacoustic events, we had the composers as performers——at the mixer control board, conducting the performance and responding (by improvisatory actions on their MIDI keyboards and controllers) to the playing of the live performers.

Although the array of 8 Mackie SR-450 speakers and the excellent mixing mitigated a number of problems, the La Esquina performance venue lacks acoustic features that are essential to the transparency and crispness of delicate, wide-spectrum works like the ones last night. (That La Esquina is an AIA venue is ironic.)

By contrast, NOVARS at Manchester University uses chilled-water cooling of the structural steel to silence the architecture of the studio and performance spaces. The total absence of architectural sounds arising from thermal expansion-contraction of the building frame—unwanted noises—is a great advantage for electro-acoustic performances at NOVARS. La Esquina, though, is a 20 x 40 meter warehouse ‘box’ with the railroad across the street, less than 50 meters away. Freight trains rumbled by every few minutes during the Interactive Gestures performance last night, an intrusive aleatoric element that seriously impaired the sonic integrity of several of the works. The roaring Burlington Northern diesel engine can ruin your ‘Time Spell’, for example, unless you happen to be casting a magical abjuration against a wizard who has morphed into a train.

Probably the works that were least affected by these complications were de Oliveira’s. The 8-channel pieces were at a sound pressure level that exceeded the ambient distractions, and the timbral and rhythmic diversity of them were riveting. The spatial articulation of sound was dramatic: we were listening to a master storyteller. The title of the event, ‘Interactive Gestures’: clinically correct. Gestures, comma, interactive, comma, in your face.

That the sound reinforcement gear and the building itself can interfere with pre-composed material is no surprise, just as the concert hall architecture and ‘system’ can interfere with traditional acoustic performance. In fact, anytime you perform a piece you transform it—its tone colors, reverb, spatialization among the channels/speakers, and amplitude shaping are different in ways that are idiosyncratic to that performance and that venue, even if the equipment is the same and the controls’ settings are the same as on a previous occasion or the same as when the piece was composed in the studio. We get a great degree of variability in the timbre, in the directed spatial distribution or trajectory of sound from the monitors, in the acoustic morphology, and in the temporal structure as perceived by members in the audience.

In the de Oliveira pieces, the acoustic spatial diffusion that was rendered via the 8-channel playback through the Mackie SR-450 300W monitors (8 loudspeakers, placed on 5-meter centers, 4 on the left side and 4 on the right side of the audience) revealed the works’ rich internal spaces. Oliveira creates a wide range of textural and gestural acoustic shapes, with semantics and phrasing that have trajectories from milliseconds to tens of seconds long—very much like intense conversation.

From sub-50Hz to sounds above 5KHz, Oliveira establishes a captivating ‘spectral occupancy’ with figures that serve as anchors to his composition/story. He structures processes around these to ‘articulate’ or define interactions of his implied ‘characters’ within the performance space.

Fluctuations are then introduced into the acoustic material either locally (at individual loudspeakers or clusters of speakers, via EQ or layering of channels and phasing effects between channels) or globally (via pitch morphing; granulation; splintering; master output from mixing console; replaying/looping; interrupting/restarting; montage). These sonic gestures evoke dynamic relationships between the elements—imply characters/actors and processes amongst them, musically.

A particular textural motion leads the live musician who plays with the fixed-media to react and respond with her own spatial and musical trajectory. Rebecca Ashe’s interpretive sense in this regard was superb. The human responses in turn introduce yet further mutations of timbral coloring, and then meta-articulations of the textural/spatial/motion arise.

For example, Rebecca Ashe introduced a sforzando spatial articulation, and this was ‘answered’ by de Oliveira in Channels 1 and 2 in response to the gesture, not only by increasing the levels to these on the console, but with chunkier density via delay and transposition layering.

 Licht book
Each interpretation creates a unique realization of a piece, just as any other chamber music performance generates a unique realization. Some reshapings were vehement and improvisational, bordering on realtime recomposition. Other reshapings were gentle and dutiful—especially those near the compositions’ ends, where the composer and performers are providing acoustic gestural ‘cues’ to the piece’s ending. Electro-acoustic may be a different language than you are used to, and the under-40 median age of the audience may be a different culture than you are used to in classical music performance, but the semantics are just as understandable and trustworthy as Beethoven.

That said, the risks in electroacoustic performance are clear. Like traditional performance practice, there is the chance that a multi-channel fixed-media interpretation that is not well-planned, or that is executed poorly, will work against a piece, no matter how fancy the performance venue architecture is and no matter how state-of-the-art the sound reinforcement gear is. All performance practice carries huge risk of error or misinterpretation. Jacob Gotlib and his collaborators did an excellent job of insuring that the performance risks were minimized. Wonderful!

Admittedly, these composers’ and performers’ works are often closer to cinema or theater than to conventional music. Whether the stories they create are conscious or unconscious, narratives are implicit in the sampling and aleatory. Every story leads to another story to another story to another story. Some of these stories are, I think, surreal or ‘pre-linguistic’ ones, in the way that de Oliveira confesses. In all, a very enjoyable evening was had by the 50 or so attendees at La Esquina last night. Bravo!

Conversation Pieces: Electro-acoustic Music and Open-Ended Dialogue

 João Pedro de Oliveira
M  y music will not break with the past or confront it … It only tries to communicate something very personal, something which may even not be communicable. I try to create something that may eventually have a glimpse of beauty.”
  —  João Pedro Paiva de Oliveira.
T  here is a small left-shift, to a position where sound becomes an expression of equivocal encounters with technology’s pervasive presence ... The ‘emblem book’ is a quirky kind of hypertext that reached its peak in Europe in the mid-17th Century. Each emblem is composed of three elements: a motto, a visual symbol, and some epigrammatic prose ... The assemblage of poetic/acoustic, visual, and literary spaces invites personal reflection on the analogies to be made between its separate components. As a form, it invites readings from several directions and offers the opportunity for each reader to reach their own individual conclusions. The various metaphors, symbols, and digressions allow room for internal flight within the space of interpretation. There is freedom to travel back and forth.”
  —  Katharine Norman, Sounding Art, p. 29.
Interactive Gestures, an evening of electroacoustic music and multimedia works, with guest artist João Pedro Paiva de Oliveira, will take place tonight, Friday, April 25 at 8:00 pm at La Esquina, at 1000 West 25th Street, Kansas City, Missouri. The event is co-sponsored by the American Institute of Architects (AIA) and by the UMKC Conservatory.

Portuguese composer João Pedro Paiva de Oliveira, visiting professor at the UMKC Conservatory, will be a featured artist. Oliveira has written in a variety of idioms, including chamber opera, requiem, orchestral, string quartet and other chamber and solo instrumental ensembles, and electroacoustic music. He currently serves as Senior Professor at Universidade de Aveiro where he teaches composition, music theory and analysis.

Interactive Gestures will include the following works by Oliveira:
  • ‘A Escaba Estreita’ (winner of Musica Nova, Czech Republic, 2005), Rebecca Ashe, alto flute;
  • ‘Time Spell’ for clarinet and tape, Cheryl Melfi, clarinet;
  • ‘Aphar’ for eight channel playback (winner of the Concours International de Musique et d’ Art Sonore Electroacoustique de Bourges, France, 2007); and
  • ‘Bloomy Girls’ for fixed media and video.
The program will also include:
  • ‘MHCHAOS’, Chris Biggs, computer, Rebecca Ashe, flute;
  • ‘Tone Goblin’ for fixed media and video, Noah Keesecker;
  • ‘Infested Readings’, Nihan Yesil;
  • ‘Tower of Babel’ for eight channel digital playback, Jacob Gotlib; and
  • ‘Third Option’, Jon Robertson, narrator, Joey Crane, guitar.
These are tremendously ‘open-ended’ pieces, as is typical for electro-acoustic music. It’s especially apropos to unite the acoustic experience with architecture and art—both of which similarly place substantial interpretive responsibilities on the viewer. Here’s an example. You’re standing in front of the Vermeer painting, one with a woman in it. Looking through a doorway, the woman is holding a lute. She has just been handed a letter by another woman. Naturally, you vicariously construct narratives in your mind, in which you contemplate the contents of the letter and confabulate the relationship between its author and the woman who is beginning to read it. (This natural human tendency is specifically what Paul Lansky’s ‘Things She Carried’ is about. And it’s also characteristic of Oliveira and other of the composers whose works are represented this evening.)

 Mary Simoni book
It’s paradigmatic in electro-acoustic music that very little is explicitly stated and that much is left to chance. But the drama is every bit as rich as more traditional forms. The music situates you in a pleasant altered state of awareness, peering as it were into your own subconscious, watching your mind form thoughts and associations.

Socially, this is not a solitary thing. Instead, it can be a shared experience that is every bit as much a stimulus to conversation and convivial speculation as any other chamber music event can be. The audience arranges itself in the midst of 8 loudspeakers, surrounded by 8 channels of exquisitely-mixed stimulations. Private confabulations become shared conversations, on topics that would never have arisen in any other way. That’s very much the spirit of the event at La Esquina this evening. Promoted on ClassicalLounge.com, it promises to be an exciting gathering. See you there!
