I've posted this before, but here it goes again:
Al Francis: Jazz Bohemia Revisited (Lost Cosmic Unity) is a wonderful album, totally obscure, never been reissued. It's as worthy of being reissued as any record I know. I have an LP copy, but I'd buy a CD reissue.
I don't know if it's been mentioned, but Henry Threadgill's Too Much Sugar for a Dime (Axiom) is another record that deserves a reissue.
