Even before stepping out of the shadows into one of the brightest solo careers of all time, singer/songwriter Carole King had already firmly established herself as one of pop music's greatest composers, with work recorded by everyone from the Beatles to Aretha Franklin. Active as a songwriter in the legendary Brill Building since the late '50s, King penned hits like Little Eva's "The Loco-Motion," the Drifters' "Up On the Roof," "Will You Love Me Tomorrow," which the Shirelles scored a number one hit with, and countless other songs that would help define pop music throughout the '60s. King eventually applied her gift for songcraft to her own albums, reaching new levels of artistry and commercial success with 1971's landmark Tapestry.
