Folk rock is a musical genre combining elements of folk music and rock music. In its earliest and narrowest sense, the term referred to a genre that arose in the United States and the United Kingdom around the mid-1960s.
British rock describes a wide variety of forms of music made in the United Kingdom. Since around 1964, with the "British Invasion" of the United States spearheaded by the Beatles, British rock music has had a considerable impact on the development of American music and rock music across the world.
