Elvis Presley made a sound so different it ushered in a new kind of music: rock and roll. He was able to combine gospel, honky-tonk, country and rhythm and blues to create a unique sound that crossed racial and cultural divides. Though he was incredibly popular, at heart, Elvis was a shy and polite man, and the demands of fame began to take a toll. While his dependence on prescription drugs cut short his life, Elvis’s influence on music and popular culture endures to this day.
