In collaboration with Charlie Haden and Trichy Sankaran, improvising trio with two Yamaha Disklavier pianos, pitch follower and event triggers, HFG (Hierarchical Form Generator) computer software, and three computer music systems responding to piano, bass and South Indian mrdangam.
"There are two basic principles of musical structure I rely on. The first is expressed by the force of attraction, (gravity, love, concentration, creation), and the second lies in the idea of repetition, (materialization, duration). My mindfulness of this constitutes the only score. I find I must wait before the beginning of each performance until I am surprised by the first sound I make and the fact that it is made. Then, I feel ready to proceed."
Developed in collaboration with Anthony Braxton, duets for MIDI grand piano, responding piano controlled by computer, with sopranino, soprano, and alto saxophones, clarinet, and flute; each piece is guided by particular interactive structures and musical shape transformation vocabularies implemented with HFG (Hierarchical Form Generator) software.

For soloist with MIDI keyboard or pitch follower, HFG (Hierarchical Form Generator) computer software, and automatically responding instruments; an adaptive extended instrument is created, which parses improvised musical material that can not be predicted in advance by employing a partial model of musical perception modeled in software.
Documentation of the first performance using HFG (Hierarchical Form Generator) interactive software for improvisation, recorded at the Western Front, Vancouver, using MIDI piano and computer, video.

In collaboration with Trichy Sankaran, for South Indian mrdangam and a computer music system that responds to the changing complexity of variations played on a rhythmic cycle and using sound samples of basic drum strokes transformed through digital signal processing to build a real–time accompaniment for the mrdangam performance.
