I've only seen him once - in a solo setting - but I've followed his career since the 70's w/Gary Bartz' Ntu Troop. It's true that he's absolutely an original - nothing like him. I like the "rubber band" analogy.
I believe they did a Ntu Troop reunion of sorts a year or two ago in Europe. It would be great to see those tunes performed live.
Needless to say, other stuff worth checking out includes his contribution to Horace Silver's "United States of Mind" trilogy, recently re-released as a 2-fer on BN. Also some nice vocalizations with Dee Dee Bridgewater on Stanley Clarke's first album - "Children of Forever".
