Ok, we're gonna try to get regular threads going. Every week you can propose a work (a piece, an album, whatever you want to call it) or cast your vote for a previously nominated piece. Every week (Sunday evening, if I can) I'll tally the votes and start a thread on the piece in question. If your nominated piece didn't make the cut, you can propose it again.
Because the music in this thread is a niche area and traffic around here is generally slow enough, lets make the threads as informative and helpful as possible. If there are any lurkers reading the forum, you are more than welcome to join in

It would also help if someone familiar with the work could go to the trouble of writing a short introduction, with youtube clips or audio samples if possible, to get the ball rolling.
So without further ado, Experimental Work of the Week #1 is
Terry Riley's "In C"
Edit - this is now a monthly thing
