Suggest one obsure album we all should hear

Rather than an album I’ll suggest a group.  Cue up anything by Infected Mushroom.

David Foreman on Arista 1976. Some may remember the only single, "Smokey China Tea". Just played after recovering stored albums. Still great.

Mount Fuji DoomJazz Corporation

Succubus

(not my favorite, I was following the unspoken but coming to be expected ’obscurity’ instructions)

aka, Mark Isham does DMT, shrooms, and acid .... while composing a leather and whips horror soundtrack.

Very much worth a listen, IMO.
Speaking of Isham, the soundtrack for Romeo Is Bleeding. uncommonly good.

Anything by “Treat Her Right”, Mark Sandman’s precursor to Morphine, “Tied To the Tracks” is fantastic storytelling and Sandman’s voice is unmistakenly cool

The Keef Hartley Band "Halfbreed"

It was voted number 3 in the All-Time 50 Long Forgotten Gems from Colin Larkin's All Time Top 1000 Albums
