Firefly Music Festival announced its 2015 lineup today. Headlining the three day festival will be rockers Kings Of Leon, The Killers, and (if the rumors are true) Paul McCartney. The programming’s unofficial mid-aughts throwback theme also includes acts like Snoop Dogg, Modest Mouse, Spoon, Matt & Kim, the Kooks, and Cold War Kids (most of whom will be supporting new albums). Also slated to appear are DJ Mustard, Cage the Elephant, Run the Jewels, Gary Clark Jr., Charli XCX, and Kid Cudi.

The Firefly Festival goes down at the Woodlands in Dover, Delaware, June 18–21. See the festival’s full lineup and ticket information here.
