John R. Cash (J. R. Cash; February 26, 1932 – September 12, 2003 ) was an American singer-songwriter. Much of Cash's music contained
themes of sorrow, moral tribulation, and redemption, especially in the
later stages of his career.[4][5] He was known for his deep, calm
bass-baritone voice,[a][6] the distinctive sound of his Tennessee Three
backing band characterized by train-like chugging guitar rhythms, a
rebelliousness[7][8] coupled with an increasingly somber and humble
demeanor,[4] free prison concerts,[9] and a trademark all-black stage
wardrobe which earned him the nickname "The Man in Black".[b]
