Since his 1955 song “Folsom Prison Blues”, Johnny Cash had been interested in performing at a prison. Backed with June Carter, whom he married later that year; Carl Perkins and the Tennessee Three, Cash performed two shows at Folsom State Prison in California on January 13, 1968. The performance, which consisted of two sets—one in the morning, and one in the early afternoon—was recorded and edited down for Johnny Cash at Folsom Prison, an album regarded by some as one of the greatest live albums of all time. The success of At Folsom Prison revitalized Cash’s career; according to Cash, “that’s where things really got started for me again”.
