Following a 1964 Albert Ayler tour, trumpeter Don Cherry remained in Europe, working on new concepts of improvising based on form itself, developing his concepts with saxophonist Gato Barbieri, vibraphonist Karl Berger & bassist J.F. Jenny Clark, composing two brilliant albums: 1966's Communion with Barbieri, Henry Grimes & Ed Blackwell; and in 1967 Symphony for Improvisers as a septet.

Extended reissue of the 1997 album bringing jazz and rock artists from 5 decades of ground-breaking work into a mysteriously lyrical band presenting 9 powerful compositions of jazz/rock fusion, led by drummer Tony Williams and bassist Bill Laswell with the stellar personnel of Pharoah Sanders, Buckethead, Nicky Skopelitis, Graham Haynes, Peter Apfelbaum, & Byard Lancaster.
