British rock music

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. Initial attempts to emulate American rock and roll took place in Britain in the mid-1950s, but the terms "rock music" and "rock" usually refer to the genre as a whole, since more styles derived in the late 50s and early 60s, such as surf and blues rock, along with many other sub genres. The term is often used in combination with other terms to describe a variety of hybrids or subgenres, and is often contrasted with pop music, with which it shares many structures and instrumentation.
