Johnny Cash was an American, multi-Grammy Award-winning country/rock and roll singer-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 demeanor, and his dark clothing, which earned him the nickname "The Man in Black." He traditionally started 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's sold over 50 million albums in his nearly 50-year career and come to be considered a musical legend.
