Phil Spector was an American musician and record producer known for his Wall of Sound sound production.
The Wall of Sound was a very dense sound with little room for details of individual instruments, exemplified in recordings such as “Da Doo Ron Ron” “Be My Baby” or “Baby, I Love You”, all released in 1963.
There is a good documentary from 1982 on Phil Spector, without his cooperation , in which Albert Goldman is recorded as saying:
“Rock ‘n’ roll is basically institutionalized adolescence. And the bottom line of rock ‘n’ roll is that it’s a baby food industry and Phil found a new formula for baby food.”
I thought that was quite funny.
