At Folsom Prison

At Folsom Prison is a live album by Johnny Cash, released on Columbia Records in May 1968. Since his 1955 song "Folsom Prison Blues", Cash had been interested in performing at a prison. His idea was put on hold until 1967, when personnel changes at Columbia Records put Bob Johnston in charge of producing Cash's material. Cash had recently controlled his drug abuse problems, and was looking to turn his career around after several years of limited commercial success. Backed with June Carter, Carl Perkins, and Cash's band, the Tennessee Three, Cash performed two shows at Folsom State Prison in Folsom, California on January 13, 1968. The resulting album consisted of 15 tracks from the first show and one track from the second.

Despite little initial investment by Columbia, the album was a hit in the United States, reaching number one on the country charts and the top 15 of the national album chart. The lead single from the album, a live version of "Folsom Prison Blues", was a top 40 hit, Cash's first since 1964's "Understand Your Man". At Folsom Prison received good reviews upon its release and has since been considered one of the greatest albums of all time. The ensuing popularity revitalized Cash's career, and led to a release of a second prison album, At San Quentin. The album was re-released with additional tracks in 1999 and as a three-disc set in 2008.
