Culled from an eclectic mix of vintage performance footage, this thrilling concert documentary follows iconic British punk rockers the Clash from an intimate studio session in 1979 to a legendary blowout concert at Shea Stadium in 1982. The band, whose members included Joe Strummer, Mick Jones, Paul Simonon and Topper Headon, also makes appearances at London's Music Machine club and Lyceum Ballroom.
