Suggest one obsure album we all should hear

 Mickey Jupps Legend

This is a fun and interesting thread.  "Obscure" seems to mean different things to different posters.  I wouldn't call this "obscure", but I hadn't heard of it until a couple of years ago.

Billy Cobham - Spectrum

Here's some European stuff that likely will be too far out of the mainstream for most Audiogoner's.

L'ensemble Raye - meme en hiver
L'ensemble Raye - Quelques pieces detachees
Begnagrad - Konzert for a broken dance
Pangea - Paxarino
and for the fans of more extreme stuff - Nimal - Distanz

Automatic Man... c 1976

The Secret Policeman's Ball. Pete Townshend's acoustic pieces are beautifully recorded. (Guitar recording is a Gibson acoustic into a mic, not via piezo pickup.)
