Suggest one obsure album we all should hear

Strictly Personal - Captain Beefheart's take on the Blues! 

Barbara Keith’s self-title debut LP on Warner Brothers circa 1971. Classic singer-songwriter with an all star studio band and very good sound.

Pink Martini - Splendor in the Grass

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...
