Guided by Sam Phillips, young musicians like Johnny Cash, Elvis Presley, Carl Perkins and Jerry Lee Lewis combined the styles of hillbilly country with the 1950s R&B sound created by artists like Muddy Waters, B.B. King, Fats Domino and Ike Turner, and changed the course of music forever. The series chronicles these young artists' often jarring and sudden meteoric rise to fame in the face of sweeping political change and social unrest.
