Suggest one obsure album we all should hear

and I violated the question, which asked for one album.

Well, thanks, everybody, for the list... just mining this list is going to be a lot of fun.

one more, just one:

has a raw "spooky" quality >> Buddy Holly: From The Original Master Tapes

Melvin Taylor & The Slack Band (self-titled)

Within the Miles Davis catalog, “Get Up With It” is pretty obscure. And it’s awesome.

Commander Cody and His Lost Planet Airmen.
