Bob Dylan has always sealed his decisions with the unexplainable. His motives for withholding the release of the magnificent 'Basement Tapes' will be as forever obscure as Brian Wilson's reasons for the destruction of the tapes for 'Smile.'

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.
