Firefly Music Festival 2015 Lineup Features KiD CuDi, Run the Jewels, DJ Mustard, Snoop Dogg and Possibly Paul McCartney

As we inch slowly toward those sweet sun-filled months, summer music festival lineups are beginning to pour in. Delaware-based Firefly Music Festival announced its artist lineup today and it is nothing short of spectacular. Headlining spots go to Kings of Leon, The Killers and, supposedly, Paul McCartney, though it is unconfirmed. Anticipated show-stealers like Snoop Dogg, ODESZA, Modest Mouse, Spoon, Matt & Kim, the Kooks, and Cold War Kids are expected to draw big crowds as most of the performers will be supporting new albums. Finally, further performers like DJ Mustard, Cage the Elephant, Run the Jewels, Gary Clark Jr., Charli XCX and Kid Cudi will appease fans of all genres. The event goes down June 18-21 at the Woodlands in Dover, Delaware. Peep the entire lineup below and check out the website here for more information.
