Suggest one obsure album we all should hear

Every time I come across a copy of Ralph Graham's album Differently in a used record store (which is often) I buy it and give it away to a friend. Great early-70s soul, halfway between Bill Withers and Johnnie Taylor. 

It was finally uploaded to the major streaming platforms, but it sounds like a crappy needle drop from a noisy old copy. 

Very obscure, but a lot of fun for fans of a certain Brazilian style flair, although it's French. 
Henri Texier - Amir and Varech

Not a very good recording, but can be entertaining...
Rick Wakeman, Journey to the Center of the Earth.

Igor Stravinsky
L'Histoire du Soldat

Deutsche Grammophon
recorded 1975
Boston Symphony Players

This never made it to CD.  It's an extraordinary performance, both musically and how well it was engineered.  Just marvelous.  

"Loop-Finding-Jazz-Records" by Jan Jelinek (2001). This minimalist electronic ambient album is quite special. Great for late night listening.

It might be difficult to find a hard copy, but you can check it out at youtube:
