2021-01: Phil Spector (producer) dies at 80

The man of the "wall of soud", producer of Let it be (the non-naked version), George Harrison's "All Things must Pass" and some other John Lennon records (and that allegedly put a gun against his head) died at 80:

Phil Spector, Famed Producer Convicted of Murder, Dead at 80 - Rolling Stone

Quoting: 

"Spector returned to the music world in 1969. A new Ronettes single, “You Came, You Saw, You Conquered,” flopped, but that same year he also released Sonny Charles and the Checkmates’ “Black Pearl,” a Number 13 hit. Now securely back in the production saddle, Spector hooked up with the Beatles. He produced John Lennon’s solo hit “Instant Karma!” and was given the task of creating an album out of the group’s abandoned Get Back sessions. The result was the Beatles final studio album, Let It Be.

Some of Spector’s critics, including Paul McCartney, were unimpressed with his string-heavy treatment of tracks such as “The Long and Winding Road.” But McCartney’s bandmates were happier with Spector’s work. George Harrison not only asked Spector to produce his triple-album, All Things Must Pass, but Lennon brought him on to co-produce The Plastic Ono Band and Imagine, albums that had an uncharacteristically spare sound for Spector. Fittingly, Lennon also had Spector, the creator of the greatest rock Christmas album of all time, produce his single “Happy Xmas (War Is Over).”
