Elvis Aaron Presley, also known simply as Elvis, was an American singer, musician and actor. He is regarded as one of the most significant cultural icons of the 20th century and is often referred to as the "King of Rock and Roll" or simply "the King". His energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, led him to great success—and initial controversy.
