British popular music and popular music in general, can be defined in a number of ways, but is used here to describe music which is not part of the art/classical music or Church music traditions, including folk music, jazz, pop and rock music.[7] These forms of music have particularly flourished in Britain, which, it has been argued, has influenced popular music disproportionately to its size, partly due to its linguistic and cultural links with many countries, particularly the former areas of British control such as United States, Canada, and Australia, but also a capacity for invention, innovation and fusion, which has led to the development of, or participation in, many of the major trends in popular music.[8] This is particularly true since the early 1960s when the British Invasion led by The Beatles, helped to secure British performers a major place in development of pop and rock music, which has been revisited at various times, with genres originating in or being radically developed by British musicians, including: blues rock, heavy metal music, progressive rock, punk rock, British folk rock, folk punk, acid jazz, drum and bass, grime, afroswing, dubstep and Britpop.
