I was on vaction the past couple of weeks, and I took along the Art Ensemble: 1967/68 Box Set that Chuck Nessa put out, it was music that I found to be overwhelming at times. I found the music very human for some reason, by that, I mean it was music that communicated directly to me. There were some amazing moments, there was a moment where I could hear a baby crying in the background, obviously a musicians baby, and it added a poingnant touch to the music. Even their use of "vocals" had a tremendous emotional resonance. Another aspect I found interesting was that the music seemed to come out of silence. Sometimes in A/G jazz, it seems as if musical discoveries come after an extended amount of music, but the AE music seems to have silence as a source of discovery. Don't know if that makes any sense or not, but there it is. I'll have to listen to this set a couple of more times to get my thoughts straight.
Edit: P.S. Chuck, if you read this know that I will (finally) get around to e-mailing you more extensive thoughts on the AE Box, I just need to listen to it more.
