John R. Cash (born J. R. Cash; February 26, 1932 – September 12, 2003) was an American countrysinger-songwriter. Much of Cash’s music contained themes of sorrow, moral tribulation, and redemption, especially in the later stages of his career. He was known for his deep, calm bass-baritone voice, the distinctive sound of his Tennessee Three backing band characterized by train-like chugging guitar rhythms, a rebelliousness coupled with an increasingly somber and humble demeanor, free prison concerts, and a trademark all-black stage wardrobe, which earned him the nickname the “Man in Black“.
