His brilliant reharmonizations were mind-boggling. I caught him in the late '80s or early '90s, a rare visit from Europe, where he played a solo concert at the JVC festival in NY (the solo piano series also featured Dave McKenna, the one time I saw him). He had an interesting history--Ornette, Mingus, Jones-Lewis, but he really flowered after he moved to Berlin. His quartet album, Sunburst, with Joe Henderson is fabulous--not just a great album, but some of Henderson's best playing too.
