The Clash were an English rock band formed in London in 1976 as a key player in the original wave of British punk rock. They have also contributed to the post-punk and new wave movements that emerged in the wake of punk and employed elements of a variety of genres including reggae, dub, funk, ska and rockabilly. For most of their recording career, the Clash consisted of lead vocalist and rhythm guitarist Joe Strummer, lead guitarist and lead vocalist Mick Jones, bassist Paul Simonon, and drummer Nicky "Topper" Headon. Headon left the group in 1982, and internal friction led to Jones' departure the following year. The group continued with new members, but finally disbanded in early 1986.

The Clash achieved commercial success in the United Kingdom with the release of their self-titled debut album, The Clash, in 1977. Their third album, London Calling, released in the UK in December 1979, earned them popularity in the United States when it was released there the following month. It was declared the best album of the 1980s a decade later by Rolling Stone. In 1982 they reached new heights of success with the release of Combat Rock, which spawned the US top 10 hit "Rock the Casbah", helping the album to achieve a 2× Platinum certification there. Their final album, Cut the Crap, was released in 1985.

The Clash's politicized lyrics, musical experimentation, and rebellious attitude had a far-reaching influence on rock, and alternative rock in particular. They became widely referred to as "The Only Band That Matters", originally a promotional slogan introduced by the group's record label, CBS. In January 2003, shortly after the death of Joe Strummer, 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 28 on its list of the 100 greatest artists of all time.
