Performed by Saul Williams and Mivos Quartet.
Jace Clayton did an album where he applied his electronic manipulations to music by Julius Eastman - The Julius Eastman Memory Depot. I couldn't find any live performances from that album, but if you read this, you should give that album a listen. Every time I do, I realize again how much I like it.
Eastman was a queer black radical in NYC in the '70's, so his piece titles tend to be provocative. Fair warning.
