Johnny Cash, known as 'The Man in Black' for his signature attire and his sympathy for the downtrodden, revitalized his career with a daring live album recorded at Folsom State Prison. At a time when his career was flagging due to drug addiction, Cash performed for the inmates, empathizing with their struggles and capturing the raw energy of the prison atmosphere. The resulting album, 'At Folsom Prison,' was a massive hit and solidified his image as a rugged outlaw with a moral compass. Cash’s deep bass-baritone voice and 'boom-chicka-boom' guitar style defined his sound. He famously crossed genres, collaborating with Bob Dylan and later covering Nine Inch Nails' 'Hurt,' a haunting performance recorded shortly before his death. Cash is one of the few artists to be inducted into the Country Music, Rock and Roll, and Gospel Halls of Fame.
