The Clash were

The Clash were a major success in the UK from the release of their debut album, The Clash, 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 month. It received wide critical acclaim; a decade later Rolling Stone magazine declared it the best album of the 1980s.

The Clash's politicised lyrics, musical experimentation, and rebellious attitude had a far-reaching influence on rock, 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 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.

Prehistory and formation: 1974–1976

Before The Clash's founding, the band's future members were active in different parts of the London music scene. John Graham Mellor sang and played rhythm guitar in the pub rock act The 101'ers, which formed in 1974. By the time The Clash came together two years later, he had already abandoned his original stage name, "Woody" Mellor, in favor of "Joe Strummer", a reference to his rudimentary strumming skills on the ukulele as a busker in the London Underground. Mick Jones played guitar in legendary protopunk band London SS, which rehearsed for much of 1975 without ever playing a live show and recording only a single demo. London SS was managed by Bernard Rhodes, a sometime associate of impresario Malcolm McLaren and a friend of the band McLaren managed, the Sexy Pistols. Jones and his bandmates became friendly with Sex Pistols Glen Matlock and Steve Jones, who would assist them as they tried out potential new members. Among those who auditioned for London SS without making the cut were Paul Simonon, who tried out as a vocalist,Gray (2005), p. 72. and drummer Terry Chimes. Nicky Headon drummed with the band for a week, then quit.

After London SS broke up in early 1976, Rhodes continued as Jones's manager. In February, Jones saw the Sex Pistols perform for the first time: "You knew straight away that was it, and this was what it was going to be like from now on. It was a new scene, new values—so different from what had happened before. A bit dangerous." At the instigation of Rhodes, Jones contacted Simonon in March, suggesting he learn an instrument so he could join the new band Jones was organising. Soon Jones, Simonon on bass, Keith Levene on guitar and "whoever we could find really to play the drums" were rehearsing. In late May, Chimes was asked to audition and became the band's full-time drummer.
