John Butcher was born in Brighton, England and has lived in London since the late 1970s. His music ranges through free improvisation, various structurings, his own compositions, multitracked saxophone pieces and work with live electronics, amplification and feedback.

He has toured and broadcast in Europe, Japan, Australia and North America, and was featured, playing solo, in the BBC TV programme Date with an Artist. Compositions include pieces for Chris Burn?s Ensemble, the Austrian group Polwechsel, the Australian ensemble Elision and the American Rova Saxophone Quartet.

David Wessel co-directs CNMAT and is a Professor of Music at UC Berkeley where he teaches computer music and music perception and cognition. He performs regularly using multi-touch surfaces as gestural controllers in conjunction with software written in Max/MSP/Jitter. His most recent controller is called the SLAB and treats gestures as continuous signals rather than event triggers.

Bill Hsu is an Associate Professor at San Francisco State University, where he teaches and does research in computer music and computer architecture. He plays piano and works with electronics, and has built systems, tools, installations and compositions, in collaboration with Peter van Bergen, John Butcher, Matthew Heckert, and Lynn Hershman, among others.
