Inducted into the Rock and Roll Hall of Fame in 1989, Spector created the "Wall of Sound" effect that involved overdubbing scores of musicians to create a massive roar, which changed the way pop records were produced.  
 
Among his session players known as the "Wrecking Crew" were guitarist Glen Campbell, pianist Leon Russell, drummer Hal Blaine and the late Sonny Bono, who learned the producer's trade under Spector.  
 
Spector produced a string of '60s hits, including the Crystals' "Da Doo Ron Ron" and "Then He Kissed Me," the Ronettes' "Be My Baby" and "Walking in the Rain," and Darlene Love's "Christmas (Baby Please Come Home)" and "(Today I Met) the Boy I'm Gonna Marry."
