Thousands of music fans will descend on Dover this June to see some of the biggest names in music for the third annual Firefly Music Festival.

After teasing fans with hints over the weekend, organizers have finally released the full festival lineup of more than 100 artists. The three headlining acts will be Foo Fighters, fronted by former Nirvana drummer Dave Grohl, hip hop group Outkast, most famous for their infectious hit "Hey Ya," and Jack Johnson, the laid-back singer-songwriter.

Other top names on the schedule for this year's festival include Arctic Monkeys, The Lumineers, Pretty Lights, Weezer, Imagine Dragons, Ziggy Marley, and Cage the Elephant.

A fourth day has been added to the festivities for the 2014 event. Festival director Greg Bostrom says with an additional day and a great slate of artists, the 2014 Firefly Music Festival will be "the most exciting Firefly yet." He says, "These changes reflect our commitment to providing our fans the premier experience they expect from us not only this year, but in the years to come."

Last year, Red Frog Events, which produces Firefly, announced plans to keep the festival in Dover for the next ten years.
