Win a Copy of the Clash’s ‘Sound System’ Box Set

On Sept. 10, Sony Legacy will release 'Sound System,' a 12-disc retrospective of the Clash. Ultimate Classic Rock is teaming up with Legacy and our sister sites Diffuser and Loudwire to give you the chance to win a copy of the set.

Packaged in a case designed to look like a camouflaged boom box, 'Sound System' contains remastered versions of five of the legendary punk band's six albums (only 1985's 'Cut the Crap,' which was recorded without guitarist Mick Jones, is omitted). This includes their 1977 self-titled debut, 1979's sprawling double-LP 'London Calling' and their commercial breakthrough, 1982's 'Combat Rock.'

In addition, there are three CDs of demos, non-album singles and B-sides, a DVD of videos, live clips and previously unseen footage. Bonus material includes a booklet with reprints of the original 'Armagideon Times' fanzine, a poster, badges and stickers.

For your chance to win, follow the instructions on the widget above. Sharing your entry across Facebook and Twitter platforms will give you more opportunities to win. The contest will expire on Sept. 9, 2013 at 11:59PM EDT. Be sure to read our official contest rules, and good luck!
