The early Stones were adolescent rockers. They were self-conscious in an obvious and unpretentious way. And they were committed to a musical style that needed no justification because it came so naturally to them. As they grew musically the mere repetition of old rock and blues tunes became increasingly less satisfying.

Atlantic's Jerry Wexler believes first-rate records are made by first-rate voices. He certainly has worked with enough of them: Clyde McPhatter, Joe Turner, La Vern Baker, Ray Charles, Otis Redding, Solomon Burke, Wilson Pickett and Aretha Franklin.

While the Beatles always had George Martin around to clean up their act, the Rolling Stones had Andrew Loog Oldham to coarsen theirs.

The Faces do not, as some have recently alleged, play badly. They are more than competent, especially at creating a mid-Sixties Rolling Stones-styled groove, as their excellent version of 'Memphis' proves.

The early Bob Dylan was compulsively drawn to the conflict between stability and the search for immortality.

Everyone eventually winds up writing about themselves - the problem is finding the best way to go about it. To write about oneself literally, in the first person, presumes a more interesting personal life and philosophy than most rock lyricists possess. John Lennon was good for one great album based on musical direct address, 'Plastic Ono Band.

Part of me believes that the completed record is the final measure of a pop musician's accomplishment, just as the completed film is the final measure of a film artist's accomplishments.
