Here's an exclusive clip from The Clash's upcoming mega box set

It's been a few months since The Clash announced the release of a super deluxe box set, but the punk pioneers are poised to release Sound System next week. The A.V. Club has an exclusive clip from the collection's sweet DVD, which contains videos and unseen footage shot by Julien Temple and Don Letts. The clip is set to The Clash's first single, "White Riot," and promises delightfully fuzzy concert scenes along with footage of proper police-hating 1970s punks. Sound System is out Sept. 9 and includes remastered studio albums, demos, B-sides, the aforementioned DVD, stickers, fanzines, a poster, and much more.
