Next week (9/10) marks the release of the Clash’s Sound System box set, a massive collection of remastered albums, demos, and merch that would impress any fan of the seminal UK punk band and we have one to give away. The 12-disc bounty includes newly mastered editions of The Clash, Give ‘Em Enough Rope, London Calling (2xCDs), Sandinista! (3xCDs), and Combat Rock, three discs of rarities, demos, non-album singles, and B-sides, and a DVD featuring unseen footage of the band from UK documentary filmmaker Julien Temple, early Don Letts-shot Super 8 film footage, all of the band’s promo videos, and previously-unseen live footage. Box set merch includes reprints of the first two Armagideon Times fanzines and a third, new issue complied and designed by bassist Paul Simonon, dog tags, pins, stickers, a Future Is Unwritten notebook designed by Harland Miller, and an exclusive Clash photo poster. And if that all sounds a bit overwhelming, no sweat, it comes with an owner’s manual, too. Check out more of the details of Sound System here and read the rules for the contest below.
