The first rock group is considered to be Bill Haley and His Comets, who released their hit song “Rock Around the Clock” in 1954. However, the term “rock and roll” was first used by DJ Alan Freed in 1951, and the genre’s roots go back even further, combining elements of blues, gospel, and country music. So, the concept of a “rock group” took shape over time, with Bill Haley and His Comets being a notable early example.
