"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."

On April 19th, 1975, at Northern Illinois University, three musicians, David Rosenboom and J.B. Floyd, pianos, and Trichy Sankaran, South Indian percussion, met in a milestone event from which emerged a unique, improvising trio with two pianos and South Indian percussion. Fortunately, it was recorded and excerpts released on a long out of print LP from A.R.C Records, Vancouver/Toronto, #ST1000, [LP record]. This CD recaptures the essential essence of the entire evening of musical discovery with previously unreleased music recovered from digitally reprocessed, re-mixed and re-mastered tapes recently discovered in diverse states of preservation; compositions include 19IV75 (Rosenboom and Floyd), Patterns for London (Rosenboom), Mrdangam Solo (Sankaran), Is Art Is (Rosenboom), and Suitable Bonus (various), Mutable Music, #17517-2, New York, 2004, [CD]

[VIDEO LINKS AVAILABLE] [SCORE AVAILABLE FOR DOWNLOAD] Three movements for viola da gamba employing cyclical gradual process techniques and parts in which melodies are drawn from the overtones of the instrument, originally realized with voltage controlled resonators and an envelope follower responding to subtle changes in bow pressure. The work may also be realized with other bowed stringed instruments, particularly the cello, which can use the notation in the original version. (Other instruments may require transpositions.) The electronic parts may also be realized with modern digital or hybrid media.
