During the 1950s two very distinct but strangely similar types of popular music arose. One was the mellow, melodic music of Nat king Cole and Perry Como, and the other was the new “rock and roll” led by Elvis Presley and Buddy Holly. Although there was generational crossover with both types of music, parents enjoyed the “feel-good innocence” of the early fifties music and its reflection of post-WWII optimism while young people liked rock and roll with its aura of rebellion and freedom from established ideals. Rock came to dominate the feel-good music in the latter half of the fifties, much to the chagrin of some parents. Entertainers like Elvis Presley led the new musical wave. His huge rise in fame combined with his interesting stage antics left some parents very uncomfortable with their children listening to his music. Elvis was not the onlyfocus of parental attacks; the music itself was soon targeted. Rock's "driving beat" was "labeled as “primitive and primal." In retrospect, the music of the 1950s and 1960s played an important role in the development of the popular music we hear today.
