One gets the impression that Elvis Presley does what his business advisors think will be most profitable. My advice to them: Put Elvis Presley in the studio with a bunch of good, contemporary rockers, lock the studio up, and tell him he can't come out until he's done made an album that rocks from beginning to end.

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.

Carole King's second album, 'Tapestry,' has fulfilled the promise of her first and confirmed the fact that she is one of the most creative figures in all of pop music. It is an album of surpassing personal-intimacy and musical accomplishment and a work infused with a sense of artistic purpose. It is also easy to listen to and easy to enjoy.

The Beatles never sounded intimidated by their idols. They never interpreted old rock; they simply played it as well and as joyfully as they knew how. On 'Rock 'n' Roll,' John Lennon does nothing but interpret old rock.

James Taylor is the kind of person I always thought the word 'folksinger' referred to. He writes and sings songs that are reflections of his own life, and performs in them in his own style. All of his performances are marked by an eloquent simplicity.

The modern recording studio, with its well-trained engineers, 24-track machines and shiny new recording consoles, encourages the artist to get involved with sound. And there have always been artists who could make the equipment serve their needs in a highly personal way - I would single out the Beatles, Phil Spector, the Beach Boys and Thom Bell.

Bob Dylan was the source of pop music's unpredictability in the Sixties. Never as big a record-seller as commonly imagined, his importance was first aesthetic and social, and then as an influence.
