At Folsom Prison was one of two legendary live albums Johnny Cash recorded in front of a prison audience in the late '60s. Part of the appeal of the records is the way Cash plays to the audience, selecting a set of songs that are all about prison, crime, murder, regret, loss, mother, God, and loneliness. Cash stimulates the audience's emotions, which in turn stimulates his performance, especially since he delivers the songs with the conviction of someone who has lived through it.
