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 Rolling Stones are violence. Their music penetrates the raw nerve endings of their listeners and finds its way into the groove marked 'release of frustration.'

As a performing group, the Beatles began by playing old rock favorites, for dancing, to tough audiences in Liverpool and Hamburg. When they began writing seriously, they discovered that they couldn't compose in the early American rock tradition.

'Band on the Run' is a carefully composed, intricately designed personal statement that will make it impossible for anyone to classify Paul McCartney as a mere stylist again.

Joni Mitchell seems destined to remain in a state of permanent dissatisfaction - always knowing what she would like to do, always more depressed when it's done.

The greatness of Mac Rebennack, alias, Dr. John, also known as John Crieux, rests on his command of the musical use of idiomatic expression. Not a technically well-endowed singer, nor a great songwriter, he leaves his mark through the discipline and control he exerts over all that he touches.

'Call Me' is not an exceptional Al Green album, but it is as solid as a rock at its center.
