Final answer:

Explanation:
An example of a 1950s Elvis-style Rocker is not one that would belong to genres outside of rock 'n' roll since Elvis Presley is closely associated with the creation and popularization of this specific genre. Presley, being a native of Mississippi and Tennessee, was heavily influenced by country music and rhythm and blues. He ingeniously merged these styles to create what we now know as rock 'n' roll, transforming the music scene of the 1950s.
Elvis Presley gained a following rather quickly, largely among the youth, although he faced stark criticism from some segments of society. His risqué performance style drew disapproval from some parents and conservative listeners who feared the influence of what they referred to as "black" music, as well as the racial integration it implied. Nevertheless, Presley's massive success and his controversial performances, such as those on The Ed Sullivan Show, reflected his iconic status as a rock 'n' roll idol of the 1950s.
Despite the initial resistance to rock 'n' roll, represented by influencers like Frank Sinatra criticizing the genre, this American musical style eventually solidified its place in American culture. By the end of the decade, businesses had produced over 600 million rock albums in response to the overwhelming demand, signifying rock 'n' roll's indelible impact on the era.
