"After three years of righteous punk anger, the Clash were ready for a change. 1976's Year Zero was fast receding, overtaken by the group's booming status as international rock stars. Recorded during 1979's hothouse summer, London Calling was to prove their magnum opus, the album that established them as masters of rock, rather than inspired insurrectionaries.
Made between US tours, it found the Last Gang well into their love/hate affair with the States, with quiffs and biker boots de rigueur and rockabilly and r'n'b part of an expanding musical repertoire."
