Suggest one obsure album we all should hear

While obscure is highly subjective, I love this post!  So I will post more than one suggestion!

My top two "out there" pics are in the new age-ish category (though new age does these recordings a disservice):

1. Deux Filles - Silence & Wisdom
2. Popol Vuh - Aguirre

If you are into the ECM jazz label, which could be obscure for some but hardly so for others, there is one release that is an absolute gem without much attention:

1. David Darling - Cello

I always loved these two 80s releases which never got too much attention (though some may disagree) ... these are in the 4AD / Dead Can Dance genre:

1. This Mortal Coil - Sixteen Days/Gathering Dust EP
2. Colourbox - Best of Colourbox 82/87

For a last song recommendation, something from a well know band:

1. The Clash - Bankrobber/Robber Dub from Black Market Clash

Michael Chapman - Life on the Ceiling and since nobody sticks to one album, Mother Goose - Stuffed

Bob Seger - Smokin’ OP’s

Van Morrison - Live at the Lions Share 1971

A lot of people seem to be struggling with the definition of "obscure."

I've been listening to a lot of Blues and Prog Rock lately, so my high recommended Prog albums (that you won't hear much about here in the States) are by Southern Empire, Riverside, Porcupine Tree (Steven Wilson), Moonrise.
Then there are some blue artists in the States that you won't hear much about but are worth hearing like Shuggie Otis (Strawberry Letter 23), Billy Paul, George Benson.
There's is a lot of old vinyl music out there that deserved to be heard and those albums you may not find in the new vinyl box and this is what makes them obscure. ChuckStereo
