Johnny Cash had been breaking new ground for a decade when At Folsom Prison suddenly made the world at large take notice. The interaction of a volatile prison population starved for entertainment and a desperately on-form Johnny Cash was electrifying. His somber machismo finally found a home. The songs, which included every prison song Cash knew ("I Got Stripes," "The Wall," "25 Minutes to Go," "Cocaine Blues," plus his own "Folsom Prison Blues") were tailored to galvanize the crowd. This set is all about atmosphere. Live at the Grand Ole Opry this ain't. The 1999 version drops the San Quentin portion of the original CD reissue, instead adding three cuts to complete the full and uncensored Folsom show. --Colin Escott
