Elvis Presley.
Since Presley family moved often, Elvis had only two things that were consistent in his childhood: his parents and music. Having problems at school, Elvis continued to surround himself with music. He listened to the radio and bought records, he often played with other ambitious musicians who lived in the neighbourhood. To listen to a wider variety of music, Elvis crossed the color line (segregation was still strongly in force in the South) and listened to African-American artists, such as B.B. King, and watched black musicians play.
By the time Elvis graduated from high school, he could sing in various styles, from pop music to gospel. More importantly, Elvis also had a style of singing and moving that was all his own. Elvis had taken all that he had seen and heard and combined it into a unique new sound.
After high school working a day job, playing at small clubs at night, and wondering if he would ever become a full-time musician, Elvis received a call from Sun Records in 1954. They wanted Elvis to sing a particular new song. After a month, Elvis recorded "That's All Right (Mama)." The song was so well liked that it was played fourteen times in a row. Elvis was so successful that Hayride show hired him to perform every Saturday for a year. It was then that Elvis stopped his day job.
High school and college students went wild for Elvis and his music. They screamed. They cheered, tearing at his clothes. For his part, Elvis put his soul into every performance. Plus, he moved his body - a lot. This was so very different than any other white performer. Adults thought he was vulgar; teenagers loved him.
