“That’s Alright Mama” was originally written and recorded by blues artist Arthur “Big Boy” Crudup in 1946. Elvis’s version, however, featured a faster tempo and a distinctive rockabilly flavor. The song’s energy and Elvis’s charismatic delivery helped it gain popularity, especially on local radio stations.

Released by Sun Records, “That’s Alright Mama” became a regional hit, marking the beginning of Elvis Presley’s rise to fame. The song’s success led to Elvis signing with RCA Records, and he went on to become one of the most influential figures in the history of popular music.
