The Kinks were an English rock band formed in Muswell Hill, North London, by brothers Ray and Dave Davies in 1964. Categorised in the United States as a British Invasion band, the Kinks are recognised as one of the most important and influential rock groups of the era. Their music was influenced by a wide range of genres, including rhythm and blues, British music hall, folk and country. Ray Davies (lead vocals, rhythm guitar) and Dave Davies (lead guitar, vocals) remained members throughout the group's 32-year run. Original members Pete Quaife (bass guitar, vocals) and Mick Avory (drums and percussion) were replaced by John Dalton in 1969 and Bob Henrit in 1984, respectively. Dalton was in turn replaced by Jim Rodford in 1978. Keyboardist Nicky Hopkins accompanied the band during studio sessions in the mid-1960s. Later, various keyboardists, including John Gosling and Ian Gibbons, were full-time members.
