London Calling is the third studio album by English rock band The Clash. It was originally released as a double album in the United Kingdom on 14 December 1979 by CBS Records, and in the United States in January 1980 by Epic Records.
The Clash recorded the album at Wessex Sound Studios in London during August, September and November 1979, following a change in management and a period of writer's black for Joe Strummer and Mick Jones, the band's lead vocalists, guitarists, and lyricists. Marking a bridge between a traditional punk rock sound and a new post-punk aesthetic, London Calling reflects the band's growing interest in a range of styles beyond their punk roots, including reggae, rockabilly, ska, New Orleans R&B, pop, lounge jazz, and hard rock. Themes explored in the songs include social displacement, unemployment, racial conflict, drug use, and the responsibilities of adulthood.
