Pop music initially drew from folk music traditions in the US and Europe, incorporating genres like ragtime, cakewalk, and foxtrot. In the 1930s, the music publishing industry moved from Tin Pan Alley to be nearer Broadway theaters in New York. Elvis Presley was a pivotal figure in popularizing pop music for integrating styles from different ethnic traditions, with Sun Records producer Sam Phillips seeking a white singer who could perform in a black vocal style, which Elvis mastered.
