Roskilde Festival Announces 2013 Lineup: Kraftwerk, the National + Sigur Ros Headlining

One of Europe's longest-running festivals -- both in terms of how many years it's been around and how many days it runs each year -- Denmark's Roskilde festival has announced its lineup for 2013. Kraftwerk, the National, Sigur Rós and Queens of the Stone Age are among the bands slated to headline this year's event, with nu-metal mavens Slipknot and R&B superstar Rihanna among the eclectic list of other artists at the top of the bill.

Also on board for the 2013 Roskilde Festival, which will run from June 29 to July 7, are Animal Collective, Of Monsters and Men, the Lumineers, Simian Mobile Disco, Black Rebel Motorcycle Club, Peter Bjorn and John, Kendrick Lamar, Miguel, James Blake and Crystal Castles. In fact, that's just a few handfuls of the nearly 200 bands set to take the stage this year. Check out the entire bill at the Roskilde Festival's official website.
