Music lovers can look forward to another festival this summer. The first-ever Firefly Music Festival has announced its lineup, and boy do they come out swinging. Rock heavyweights the Black Keys, Jack White, the Killers and over 30 more acts will rock Dover, Del., this July.

The lineup mainly consists of rock and some hip-hop artists. Also joining the party will be Seattle hipsters Death Cab For Cutie and festival favorites the Flaming Lips, plus Passion Pit, Cake, Lupe Fiasco, Young the Giant, OK Go, R&B star John Legend and more.

The festival grounds will be located near Dover International Speedway, on 87 acres worth of wooded land. "We're thrilled to announce Firefly Music Festival as the East Coast's premier music experience and are set on delivering an unforgettable weekend complete with top tier talent and unique attractions," said Joe Reynolds, owner of Red Frog Events, the producers of Firefly. "We look forward to bringing Firefly to life in July."

Though certainly the main focus, music isn't the only entertainment option available at Firefly. Organizers have planned everything from craft beers and a wine garden to multiple food choices and hot-air balloon rides. Imagine riding in a hot air balloon over a psychedelic Flaming Lips set -- as if seeing them doesn't get you high enough.

The Firefly Music Festival goes down July 20-22. Weekend tickets start at $178 and go on sale this Thursday at Attendance is expected to be 30,000-40,000 people during each day of the event.
