This is an Impulse stereo pressing on the Red and Black label with RVG stamps in the dead wax. It's made from the same metalwork as my original copy (same exact stampers) and in a quick comparison I thought this one sounded at least as strong. (The only reason I didn't do a full-on shootout was I didn't want to give myself a reason to keep both! I can be highly irrational when it comes to my favorite albums.)
Both sides sound wonderful -- big and present with excellent definition to the bass. There's a touch of surface noise and some lightly ticks spots, but nothing that came close to overpowering the music. And the cover is as nice as I've seen on an early pressing -- a real thing of beauty!
This is an album I'm wild about and the 5 star Allmusic review is on point: "The Black Saint and the Sinner Lady is one of the greatest achievements in orchestration by any composer in jazz history... The result is one of the high-water marks for avant-garde jazz in the '60s and arguably Mingus' most brilliant moment."
Vinyl: VG+ (clean)
Cover: EX (absolutely gorgeous)
Play notes: Incredible sound. Light to moderate surface noise in spots.
