This documentary combines recent interviews and old footage to provide a comprehensive view of The Clash, one of the world's most influential rock bands. Footage from old club shows and stadium concerts is intercut with interviews with band members Mick Jones, Paul Simonon, Topper Headon, and Joe Strummer. The Clash began as rebellious punks eager to combine their influences: Simonon leaned towards reggae, and Jones leaned toward harder-edged British rock, while Strummer favored American R&B. Despite various fights and conflicts, The Clash emerged as "the only band that mattered," a punk rock band which ventured beyond punk to create a unique and unforgettable sound. WESTWAY TO THE WORLD documents their beginnings, their rise to stardom, and their collapse.
