Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was one of the most popular American singers of the 20th century. A cultural icon, he is widely known by the single name Elvis. He is often referred to as the "King of Rock and Roll" or simply "the King".

Born in Tupelo, Mississippi, Presley moved to Memphis, Tennessee, with his family at the age of 13. He began his career there in 1954, working with Sun Records owner 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 the most important popularizer of rockabilly, an uptempo, backbeat-driven fusion of country and rhythm and blues. RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who would manage the singer for over two decades. Presley's first RCA single, "Heartbreak Hotel", released in January 1956, was a number one hit. He became the leading figure of the newly popular sound of rock and roll with a series of network television appearances and chart-topping records. His energized interpretations of songs, many from African American sources, and his uninhibited performance style made him enormously popular—and controversial. In November 1956, he made his film debut in Love Me Tender.

Samuel Cornelius Phillips (January 5, 1923 – July 30, 2003), better known as Sam Phillips, was an American businessman, record executive, record producer and DJ who played an important role in the emergence of rock and roll as the major form of popular music in the 1950s. He was a producer, label owner, and talent scout throughout the '40s and '50s. He most notably founded Sun Studios and Sun Records in Memphis, Tennessee. Through Sun, Phillips discovered such recording talent as Howlin' Wolf, Carl Perkins, Jerry Lee Lewis and Johnny Cash. The height of his success culminated in his launching of Elvis Presley's career in 1954. He is also associated with several other noteworthy rhythm and blues and rock and roll stars of the period. Phillips sold Sun in 1969. He was an early investor in the Holiday Inn chain of hotels.

Phillips was the youngest of eight children, born on a farm near Florence, Alabama to poor tenant farmers. As a child he picked cotton in the fields with his parents alongside black laborers. The experience of the workers singing in the fields left a big impression on the young Phillips. Travelling through Memphis with his family in 1939 on the way to see a preacher in Dallas, he slipped off to look at Beale Street, at the time the heart of the city's music scene. "I just fell totally in love," he later recalled.

Roy Kelton Orbison (April 23, 1936 – December 6, 1988) was an American singer-songwriter, best known for his distinctive, powerful voice, complex compositions, and dark emotional ballads. Orbison grew up in Texas and began singing in a rockabilly/country and western band in high school until he was signed by Sun Records in Memphis. His greatest success came with Monument Records between 1960 and 1964, when 22 of his songs placed on the Billboard Top Forty, including "Only the Lonely", "Crying", and "Oh, Pretty Woman". His career stagnated through the 1970s, but several covers of his songs and the use of "In Dreams" in David Lynch's Blue Velvet revived his career in the 1980s. In 1988, he joined the supergroup Traveling Wilburys with George Harrison, Bob Dylan, Tom Petty, and Jeff Lynne and also released a new solo album. He died of a heart attack in December that year, at the zenith of his resurgence. His life was marred by tragedy, including the death of his first wife and his two eldest sons in separate accidents.
