Rock&Roll Rock and roll (often written as rock & roll or rock 'n' roll ) is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s, primarily from a combination of the blues , country music and gospel music .

An early form of rock and roll was rockabilly , which combined country and jazz with influences from traditional Appalachian folk music and gospel.

12. Folk rock By the 1960s, the scene that had developed out of the American folk music revival had grown to a major movement, utilising traditional music and new compositions in a traditional style, usually on acoustic instruments. In America the genre was pioneered by figures such as Woody Guthrie and Pete Seeger and often identified with progressive or labor politics . In the early sixties figures such as Joan Baez and Bob Dylan had came to the fore in this movement as singer-songwriters.Dylan had begun to reach a mainstream audience with hits including " Blowin ' in the Wind " (1963) and " Masters of War " (1963), which brought " protest songs " to a wider public, but, although beginning to influence each other, rock and folk music had remained largely separate genres, often with mutually exclusive audiences.
