roach, thanks for the recommendation. I'll see if I can track it down. My first exposure to the whole piece was actually at Juilliard where an 80 minute long dance was choreographed to it. The performance featured 55 dancers sliding down a massive ramp while a percussion ensemble played. From talking to the performers, reconciling the way dancers think (by counting beats) to the way percussionists think (setting up the phase and waiting for it to come back around) was the biggest challenge. Whatever the case, it was really amazing. Because of the resources required, I highly doubt it will ever be performed again, which is a real shame.
Choreography was by Elliot Feld and the piece was called "Sir Isaac's Apples".
I'll check that CD out, and let you know if I can't find it anywhere. Thanks again.
*edit - added a picture of the ramp so no one would think I exaggerated about the size. Notice the two workers walking along the top.
