It’s July sixth, and on this day in 1954… Elvis Presley returned to Sun Studio with Scotty Moore and Bill Black to record the second song for what would become his debut single. Just the night before, they had captured lightning in a bottle with “That’s All Right.” Now they needed a B-side. The trio settled on a hopped-up version of Bill Monroe’s “Blue Moon of Kentucky,” transforming the bluegrass waltz into a driving rockabilly tune. The pairing of these two songs marked the official beginning of Elvis’s recording career—and the birth of a new sound in American music.
