Johnny Cash (born J. R. Cash, February 26, 1932 – September 12, 2003) was a multi Grammy Award-winning influential American country and rock and roll singer and songwriter. Cash was the husband of country singer and songwriter June Carter Cash.
Cash was known for his deep, distinctive voice, the boom-chick-a-boom or "freight train" sound of his Tennessee Three backing band, his dark clothing, and demeanor, which earned him the nickname "The Man in Black." He started all his concerts with the simple introduction "Hello, I'm Johnny Cash." Much of Cash's music, especially that of his later career, echoed themes of sorrow, moral tribulation, and redemption. His signature songs include "I Walk the Line", "Folsom Prison Blues", "Ring of Fire", and "Man in Black".
He sold over 50 million albums in his nearly 50 year career and is generally recognized as one of the most important musicians in the history of American popular music.
