The Clash were an English punk rock band that formed in 1976 as part of the original wave of UK punk. Along with punk rock, they experimented with reggae, ska, dub, funk, rap and rockabilly. For most of their recording career, The Clash consisted of Joe Strummer (lead vocals, rhythm guitar), Mick Jones (lead guitar, vocals), Paul Simonon (bass, backing vocals, occasional lead vocals) and Nicky "Topper" Headon (drums, percussion). Headon left the group in 1982, and internal friction led to Jones's departure the following year. The group continued with new members, but finally disbanded in early 1986.

The Clash were a major success in the UK from the release of their self-titled debut album in 1977. Their third album, London Calling, released in the UK in December 1979, brought them popularity in the United States when it came out there the following year. It received wide critical acclaim; a decade later Rolling Stone magazine declared it the best album of the 1980s.

The Clash's politicized lyrics, musical experimentation, and rebellious attitude had a far-reaching influence on rock, alternative rock in particular. Their record label's A&R director dubbed them "The Only British Band That Matters," which fans picked up and transformed into "The Only Band That Matters". In January 2003 the band—including original drummer Terry Chimes—were inducted into the Rock and Roll Hall of Fame. In 2004, Rolling Stone ranked The Clash number 30 on their list of the 100 Greatest Artists of All Time.
