Task: Question Answering
Input (English): Passage: Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was an American singer and actor. Regarded as one of the most significant cultural icons of the 20th century, he is often referred to as the "King of Rock and Roll" or simply "the King".
Presley was born in Tupelo, Mississippi, and relocated to Memphis, Tennessee, with his family when he was 13 years old. His music career began there in 1954, recording at Sun Records with producer Sam Phillips, who wanted to bring the sound of African-American music to a wider audience. Accompanied by guitarist Scotty Moore and bassist Bill Black, Presley was a pioneer of rockabilly, an uptempo, backbeat-driven fusion of country music and rhythm and blues. In 1955, drummer D. J. Fontana joined to complete the lineup of Presley's classic quartet and RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who would manage him for more than two decades. Presley's first RCA single, "Heartbreak Hotel", was released in January 1956 and became a number-one hit in the United States. With a series of successful network television appearances and chart-topping records, he became the leading figure of the newly popular sound of rock and roll. 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, made him enormously popular—and controversial.
In November 1956, Presley made his film debut in Love Me Tender. Drafted into military service in 1958, Presley relaunched his recording career two years later with some of his most commercially successful work. He held few concerts however, and guided by Parker, proceeded to devote much of the 1960s to making Hollywood films and soundtrack albums, most of them critically derided. In 1968, following a seven-year break from live performances, he returned to the stage in the acclaimed television comeback special Elvis, which led to an extended Las Vegas concert residency and a string of highly profitable tours. In 1973, Presley gave the first concert by a solo artist to be broadcast around the world, Aloha from Hawaii. Years of prescription drug abuse severely compromised his health, and he died suddenly in 1977 at his Graceland estate at the age of 42.
Presley is the best-selling solo artist in the history of recorded music. He was commercially successful in many genres, including pop, country, blues, and gospel. He won three competitive Grammys, received the Grammy Lifetime Achievement Award at age 36, and has been inducted into multiple music halls of fame.
