i nearly forgot. i picked up this really interesting record late last week based on the pitchfork review i read.

William Basinski - The Disintegration Loops II

Apparently there are 4 discs in total. #2 is the only one i've seen for as long as i've looked. there are 2 tracks on it, the first is 30 minutes, the second is 40 or so.

i think the review does a great job of describing the sound...
In essence, Basinski is improvising using nothing so much as the passage of time as his instrument, and the result is the most amazing piece of process music I've ever heard, an encompassing soundworld as lulling as it is apocalyptic. A piece may begin bold, a striking, slow-motion slur of ecstatic drone, and in the first minute, you will notice no change. But as the tape winds on over the capstans, fragments are lost or dulled, and the music becomes a ghost of itself, tiny gasps of full-bodied chords groaning to life amid pits of near-silence.
see if this interests you as much as it did me: http://www.pitchforkmedia.com/record...on-loops.shtml
