The Killers, Foster the People, Modest Mouse, Hozier & Kid Cudi also on the bill.

The Firefly Music Festival has announced its 2015 lineup, which will include Kings of Leon, Snoop Dogg, BastilleFoster the People and many more. The festival will take place June 18-21 at The Woodlands of Dover International Speedway in Dover, Delaware.

This is the festival's fourth consecutive year at the Dover International Speedway. Firefly has brought in heavy-hitters from the rock world as headliners every year -- Jack White and the Black Keys in 2012, the Red Hot Chili Peppers and Tom Petty in 2013, and the Foo Fighters in 2014. This year Morrissey, Modest Mouse and Hozier will burnish the festival's rock credentials. Meanwhile, Zedd and Empire of the Sun will provide dance-friendly beats, and acts like Run the Jewels will keep hard-core hip-hop fans happy.

The festival has not yet announced its third headlining act. Tickets will go on sale later this year; you can check out the rest of the lineup below.
