Elvis Presley
Elvis Presley walked into Sun Studio a Memphis truck driver and walked out the blueprint for the rock and roll frontman, welding Black rhythm and blues to white country and gospel until the seams disappeared. His hip-shaking 1956 breakthrough scandalized as much as it thrilled, and for the rest of his career he moved between raw rockabilly, movie-star balladry, and Vegas spectacle. He died in 1977, but the King title never really passed to anyone else.

Arthur Crudup1940s · Delta blues
Elvis's very first single at Sun Studio was a cover of Crudup's 'That's All Right,' cut almost on a whim during a break in the session — Crudup's loose, electric blues phrasing became the seed of Presley's whole early sound.

listen forPlay Crudup's 1946 original 'That's All Right' next to Elvis's 1954 version — same lyrics, same lazy blues swing, but Elvis speeds it up and pushes the energy toward something new.
Bill Monroe1940s · Bluegrass
For the B-side of that same first single, Elvis took Monroe's stately bluegrass waltz 'Blue Moon of Kentucky' and doubled its tempo into something closer to rock and roll.

listen forHear Monroe's mandolin-driven, waltz-time original, then Elvis's galloping cover — the melody and words are unchanged, but the rhythm section turns a bluegrass standard into a rockabilly stomp.
Dean Martin1950s · Traditional pop / Easy listening
As Elvis's career matured, his sound increasingly embraced the relaxed, romantic croon of pop stylists like Dean Martin, softening the rockabilly edge for ballads and movie soundtracks.

listen forListen to the warm, unhurried croon of Martin's 'That's Amore,' then Elvis's 'Can't Help Falling in Love' — the phrasing has the same easy, old-world romanticism underneath Presley's own vocal signature.
