Might have to pick this one up. Johnny Cash played a legendary gig at Folsom Prison in 1968 that resulted in a classic killer live recording. Now, Sony Legacy has (re)released Johnny Cash At Folsom Prison,a 2 CD/1 DVD set that includes not only the classic tracks (and a lot of unreleased ones as well) but a new documentary about it produced by award-winning director Bestor Cram and Cash biographer Michael Streissguth.

The documentary was screened recently at the San Francisco Bay Area’s Noise Pop Festival and reviewed by Ben Richardson:

Tragedy is likewise abundant in the little-known story of Glen Sherley, another Folsom inmate. Serving five-to-life for armed robbery, his song “Greystone Chapel” found its way into Cash’s hands the night before the concert. Taken with the plight of the prisoner and the power of his music, Cash and his band learned the tune overnight, performing it as the final song in the set in front of a stunned Sherley, who was seated in the front row. Cash continued to champion Sherley’s career after his eventual release, and the film depicts this obscure chapter in Cash’s life, and its sad conclusion, with captivating verve.
