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'
Silver Metre
Silver Metre - S/T (1969) (National General Records vinyl) (FULL LP) - YouTube

FYI, Wishbone Ash - Argus beat out Jethro Tull’s "Thick as a Brick" for Best Album of the Year in England.
One of my all-time-faves. Not Led Zeppelin good but a solid drinking album.

Also listen to Ten Years After (Elvis) - "Cricklewood Green".
Johnny Winter - "Second Winter".
These are mainstream albums to my generation but you sound like a youngster...
