The case can easily be made that no side man of our time has had a greater presence and more significant role in the success of his band leader than Clarence Clemons of the E Street Band had on Bruce Springsteen.  When Bruce sang '...the change was made uptown when the big man joined the band'  on Born To Run's Tenth Avenue Freeze-Out he sent a clear message about the impact Clemons would have in re-writing the future of Rock & Roll.  The magnificent role Clemons played by infusing the music of the E Street Band with elements of soul, funk and dynamic brilliance will live on in his absence, but the idea that we will never be able to experience the exhilaration of his soaring solos punctuating Springsteen's great songs in concert leaves a void that can never be filled.  Clarence Clemons died Saturday (6/18) of complications after suffering a stroke six days earlier.
