There may be no more pivotal figure in the development of early rock music than Sam Phillips, the owner of Sun Records in Memphis.
He recorded and introduced the likes of Johnny Cash and Jerry Lee Lewis, and even Elvis Presley.
Phillips himself was one of the first inductees in the Rock And Roll Hall of Fame.
He and his work are profiled in the new hardcover book Sam Phillips: The Man Who Invented Rock 'n' Roll, by Peter Guralnick.
We'll grab some of the old records from the library and get Guralnick on the phone for a tuneful visit.
