That's All Right Mama
Label: Promo Sound
Released in March of 1956, Elvis Presley ushered in the rock 'n' roll era. The first rock record to top a million in sales, it laid the blueprint for pretty much everything that followed. Highlighted by a handful of the famed Sun Sessions songs, Elvis' supernatural vocals and the country-billy backing of Scotty Moore and Bill Black, it remains a touchstone to this day.
