From the liner notes:
"For us, composing a piece of music is building a new instrument, an instrument whose behavior makes up the performance. We act at once as performer, composer and instrument builder, in some ways working more like sculptors than traditional musicians." - Tim Perkis, John Bischoff
Recorded at Mills College Concert Hall (Oakland, California, USA) on 4/14/89 except Clicks, Audio wave & Happy trails at Philip Perkins' Studio.
