Elvis Presley, "Good Rockin' Tonight" (1954)
For Elvis' second Sun single, Phillips chose the semi-obscure jump-blues number "Good Rocking Tonight," originally written by R&B singer Roy Brown in 1947. While Presley sounds clearly energized on the track, it's Moore's pair of expressive guitar solos, coming first around the :40 mark and again a minute later, that steal the show. "They were completely off the cuff," Moore explained of his approach to soloing. "You might get a bass riff or something, as a hook for the song, but the solos were strictly ad lib. Even now I'll go back and I can't play note for note what I played then. I can get the general feel of it but I can never go back and hit it note for note. It just doesn't feel right."
