Suggest one obsure album we all should hear

Socrates García Latín Jazz Orchestra, Back Home. Pure sonic bliss!

Azam Ali - From Night to the Edge of Day

Dodie - Intertwined (may not count as obscure any more)

Sleepytime Gorilla Museum - Grand Opening and Closing

Kepler Quartet - Ben Johnston String Quartets Nos 6, 7 & 8 (100% intonal notation, may melt your brain)

 Angel!
great band!

@knighttodd  - I saw Angel, in support of their new album (at that time) "White Hot". Opening act was Godz and the headliner was Blue Oyster Cult. Rupp Arena, Lexington, KY, April 2, 1978. Still have the ticket stub :~) and a distinct memory of seeing the lead singer - Punky Meadows for the first time. Talking about Glam Bands. Wow! Made a statement......

Everyone should experience CRACK THE SKY unfortunately because of their label, it nearly impossible to get their early stuff. If you come Across the first Three albums, "Animal Notes" "Safety in Numbers" and the "Live" album you will be forever changed.
