With London Calling, their third album in as many years, the Clash broke out of the U.K. punk ghetto to take on the rest of the world. More than just a clarion call from the band to their ranks, the album revealed a level of musicianship and vision that set The Clash apart from their peers. It hinted at the group's broader influences and future explorations, proving that punk rock could grow to encompass all manner of music, from dub reggae to rockabilly. This record earned them the tag "the only band that matters." The world was listening, and in the years to come, an army of bands would answer The Clash's call.
