Ting, ting, ting, ting, ting, ting, ting, ting...that's how this starts, with a drumming pulse on the top Cs on a piano. Then gradually, a whole tapestry of interlocking sounds starts to unfold, and you're slowly getting immersed in 'In C'. You don't really listen to this piece; the effect is much more like that aforementioned 'immersion', as the very gradual shifting of the patterns is more like organic growth, instead of the architectural jumps and skips found in Philip Glass or Steve Reich's works. How this is accomplished is by the use of a very selective variant on chance processes; since performers aren't given direct instructions on when to change from one ostinato to the next, this slow, 'oozing' shifting occurs, and it's quite fascinating (as opposed to what one reviewer here seems to think). It's certainly not an easy work to wrap your head around, unlike Glass, etc, but both the music and the ideas behind it are most rewarding. A critical work.
