This guy played on the soundtrack to Alejandro Jodorowsky's surreal masterpiece "The Holy Mountain" and on Ornette Coleman's classics: "The Shape of Jazz to Come" and "Free Jazz". That alone should be reason enough to listen to this.
He might not be as famous as Miles Davis but he's just as crazy and diverse. This album is jazz with hints of Eastern European and African music, Bitches Brew-esque spaced funk, and psychedelic/krautrock experimentation. It's not easy to pin down and it's so original you need to listen for yourself.
