Ian Anderson (yes, as in Jethro Tull) Divinities, twelve dances with God, instrumental masterpiece and very well produced in his basement in Scotland 

Robert Lucas - Luke and the Locomotives
Audioquest's foray into recording ('90s?).

Big Man Mambo - YouTube

I’m a big fan of Mr. Bungle, so when the guy at the record store pulled out this “rarity” out and put it on, I was sold.
