plays to 2,000 inmates at Folsom State Prison
, Folsom, California, USA. Although it is far from his first show at a prison (he'd been playing for inmates since the Texas Prison Rodeo at Huntsville in 1956) it will become his most famous, sometimes described as "the single most important day in the career" of Johnny Cash
. The performance will be released as Johnny Cash At Folsom Prison
. Also on the bill are Carl Perkins
and The Statler Brothers. The band's van and possessions are searched as they enter the prison but evidently none too thoroughly, as Cash is known to have used amphetamines to help energise his performance at the show. The visiting entourage also includes Los Angeles Times writer Robert Hilburn and photographer Jim Marshall, who were paid to document the album for the liner notes. Cash opens the performance with Folsom Prison Blues.
