Sam Phillips, meanwhile, was always on the lookout for someone who could bring to a broader audience the sound of the black musicians on whom Sun focused. As Phillips' secretary Marion Keisker reported, "Over and over I remember Sam saying, 'If I could find a white man who had the Negro sound and the Negro feel, I could make a billion dollars.'" In June, he acquired a demo recording of a ballad, "Without You", that he thought might suit the teenage singer. Presley came by the studio, but was unable to do it justice.

Despite this, Phillips asked Presley to sing as many numbers as he knew. He was sufficiently affected by what he heard to invite two local musicians, guitarist Winfield "Scotty" Moore and upright bass player Bill Black, to work something up with Presley for a recording session.

The session, held the evening of July 5, 1954, proved entirely unfruitful until late in the night. As they were about to give up and go home, Presley took his guitar and launched into a 1946 blues number, Arthur Crudup's "That's All Right". Moore recalled, "All of a sudden, Elvis just started singing this song, jumping around and acting the fool, and then Bill picked up his bass, and he started acting the fool, too, and I started playing with them. Sam, I think, had the door to the control booth open ... he stuck his head out and said, 'What are you doing?' And we said, 'We don't know.' 'Well, back up,' he said, 'try to find a place to start, and do it again.'" Phillips quickly began taping; this was the sound he had been looking for.

Three days later, popular Memphis DJ Dewey Phillips played "That's All Right" on his Red, Hot, and Blue show. Listeners began phoning in, eager to find out who the singer was. The interest was such that Phillips played the record repeatedly during the last two hours of his show. Interviewing Presley on-air, Phillips asked him what high school he attended in order to clarify his color for the many callers who had assumed he was black. During the next few days, the trio recorded a bluegrass number, Bill Monroe's "Blue Moon of Kentucky", again in a distinctive style and employing a jury-rigged echo effect that Sam Phillips dubbed "slapback". A single was pressed with "That's All Right" on the A side and "Blue Moon of Kentucky" on the reverse.

Yes, others did forms of it earlier. Some may have even done it better. But Elvis was the embodiment, the confluence through which all earlier musical forms were fused - R&B / Gospel, country and popular. Previous musical rivers flowed to and through 1954-56 Elvis and then started diverging again starting July 5th, 1954.

And culturally Elvis was the rock god template, the original gangsta. Rags to riches, flashy clothes, flashy cars, flashy crib, lots of women, and the first to have a posse.
