Johnny Cash was an American singer-songwriter, guitarist, actor, and author. He is one of the best-selling music artists of all time, having sold more than 90 million records worldwide. Although primarily remembered as a country music icon, his genre-spanning songs and sound embraced rock and roll, rockabilly, blues, folk, and gospel. This crossover appeal won Cash the rare honor of being inducted into the Country Music, Rock and Roll, and Gospel Music Halls of Fame.
Cash was known for his deep, calm bass-baritone voice, the distinctive sound of his Tennessee Three backing band characterized by train-sound 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". He traditionally began his concerts by simply introducing himself, "Hello, I'm Johnny Cash," followed by his signature song "Folsom Prison Blues".
Much of Cash's music contained themes of sorrow, moral tribulation, and redemption, especially in the later stages of his career. His other signature songs include "I Walk the Line", "Ring of Fire", "Get Rhythm", and "Man in Black".
