Whether one catches the feeling on a record is a subjective matter. How can you be sure? The machinery can hold out the promise of at least mechanical perfection.

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.
