Suggest one obsure album we all should hear


I love when I discover an album that's new to me, and great.Please share one so we can all broaden our musical horizons.

Mine is:
Wishbone Ash  'Argus'
1111art
"Live at the Bill Graham's Fillmore West" featuring Mike Bloomfield, Taj Mahal, Nick Gravenites etc. (One of my all time favorites except skip the song "Oh Mama" because Bloomfield's singing is as bad as his guitar playing was great)

Magazine's "Play" album

"June 1, 1974  Kevin Ayers- John Cale-Brian Eno-Nico"
Babe Ruth...First Base
Iron Butterfly...Metamorphosis 
Chick Corea and Return to Forever...Musicmagic
Fools Gold...Mr. Lucky
