Comprising virtually everything the Clash recorded, 'Sound System' traces the band's journey from scrappy punk agitators to world-conquering genre slayers. Led by iconic frontman Joe Strummer and guitarist Mick Jones, the foursome played everything from rockabilly and dub reggae to disco and hip-hop, and highlights of this must-own package include their incendiary 1977 self-titled debut, 1979's virtually flawless 'London Calling' and 1982's 'Combat Rock,' the commercial breakthrough that produced the hits 'Rock the Casbah' and 'Should I Stay or Should I Go.'

Of course, 'Sandinista!' (1980) and 'Give 'Em Enough Rope' (1978) ain't bad either, and as if that -- plus all of the demos, live cuts, b-sides, alternate takes and videos -- weren't enough, 'Sound System' includes badges, stickers, fanzines and dog tags, all packaged in a box that looks like a ghetto blaster. If you're a Clash fan, you need this. 'Nuff said.

The contest runs through 11:59PM EST on Sept. 9 -- click here for the official rules.
