September 10, 2013 will see the release of The Clash‘s huge 13-disc box set entitled Sound System. The collection includes remastered versions of the group’s five studio albums, as well as remixes, demos, outtakes, and alternate versions of classic songs. It also includes video footage, such as the band’s very first rehearsal in 1976, a 1977 gig at Sussex University, and their 1981 residency at the New York club Bonds.
