BEST OF JOHNNY CASH: CURB Records. Cash grew up poor, served in the Air Force and later sold appliances door-to-door before starting his recording career at Sun Records in 1955. He was a voice of rebellion and authenticity who changed the face of music, bridging country and rock 'n' roll to create his own unmistakable sound. Johnny Cash was an outlaw before today's rebels were born, and he did all this before turning 30.
