Suggest one obsure album we all should hear

Olu Dara - In the World

I have a solid list that you guys may not have heard

Oteil and Peacemakers  - Love of a lifetime or Believer

Some offshoot not well known Garcia stuff unless you are a head.  All might find them interesting
Hooterall
Fireup

Diga Rythm Band- Mickey Hart

Danny Cox- Life at the family dog or other stuff from him

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.
