Got to be some love out there for the great man. His grunting, humming, moaning accompaniment to his long improvisations on piano are reasonably well-known, less so his additions to the classical canon and his talent on soprano sax. Saw him live back in the 70s in a smoky little jazz club in Boston, sitting exactly one metre behind his elbow. Completely hooked me. My favourite work of his is this, the Survivors’ Suite (of which only the start is available)
And here’s a fitting article on him
