A few more obscure worthies...
Roosevelt Wardell - The Revelation (Riverside). An unquestionably obscure figure , he'd be in his mid-seventies if still living . If Chris Albertson (who wrote this album's liner notes) has more info about him I hope he'll share it here .
Chris Anderson - Inverted Image (Jazzland) . While apparently not representative of his live playing , this album is one of only a few made by the estimable pianist .
Steve Kuhn - 1960 (PJL) . Previously unissued Kuhn demo (briefly available on a Japanese CD) has the pianist in a trio with Scott LaFaro and Pete LaRoca . Good sound , brief playing time .
Mike Nock - Between Or Beyond (MPS) . Essentially a Fourth Way recording minus Michael White , this one certainly has a period feel (1970) with lots of processed e-piano , but some nice acoustic playing as well .
Paul Knopf - The Outcat (Playback)
Paul Knopf - Enigma Of A Day (Playback) . See my comments in the Paul Knopf thread .
