Best sounding mono recording (vinyl)


What is the best sounding mono record you own? I'll start the discussion with:

Getz Au Go Go. Verve recording in 1964 in Greenwich Village.
Live performance with Stan Getz Quartet featuring Astrud Gilberto.

There's also a stereo version of this, but the sound of this mono recording is so 3-dimensional. Great front to back imaging.

My go to is an old Ken Kessler favorite - The Chordettes s/t

While this will will sound fun on just about any system as you improve you’ll find out how much layering and detail is hidden in the grooves
Actually, the Richie Havens  "Mixed Bag" lp I played earlier, sounded very good. Sundazed/mono
The Everly Brothers' Cadence Records recordings. The UK Ace LP reissues are better sounding than those of Rhino Records.
Last time I listened to it, I thought "Pet Sounds" DCC, sounded remarkable in mono.
