By the time Eric Clapton launched his solo career with the release of his self-titled debut album in mid-1970, he was long established as one of the world's major rock stars due to his group affiliations -- the Yardbirds, John Mayall's Bluesbreakers, Cream, and Blind Faith -- which had demonstrated his claim to being the best rock guitarist of his generation. That it took Clapton so long to go out on his own, however, was evidence of a degree of reticence unusual for one of his stature. And his debut album, though it spawned the Top 40 hit "After Midnight," was typical of his self-effacing approach: it was, in effect, an album by the group he had lately been featured in, Delaney & Bonnie & Friends.
