Sound System is a box set collection by The Clash released in September 2013. The box contains the band's studio albums (minus their final album; Cut the Crap) newly re-mastered by Mick Jones, with a further three discs featuring demos, non-album singles, rarities and B-sides, a DVD with previously unseen footage by both Don Letts and Julien Temple, original promo videos and live footage, plus an owner's manual booklet, reprints of the band's original 'Armagideon Times' fanzine and merchandise including dog tags, badges, stickers and a poster. The boom box packaging was designed by Paul Simonon. The set was released simultaneously with 5 Album Studio Set, which contains only the five studio albums, and a greatest hits package titled The Clash Hits Back.
