"No one person started rock 'n' roll. It was a black and white alloy of Fats Domino, Lloyd Price, Ike Turner, Hank Williams, Joe Turner, Louis Jordan, Ray Charles, Little Richard, Jerry Lee Lewis, Chuck Berry, Bo Diddley, Buddy Holly - and Elvis Presley. Presley himself never claimed to have invented rock 'n' roll. He always talked about how much he was influenced by black gospel music and the blues, which he listened to on the radio growing up in Tupelo, Miss. His absorption of these black influences is what allowed him to have a black feel to his music when he entered the Sun Records recording studio 50 years ago." By JACK NEWFIELD | September 21, 2004
