Suggest one obsure album we all should hear

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
