Despite all of the competition, Firefly has managed to become one of the country’s premier festivals in just two years’ time. Now entering its third iteration, Firefly has somehow managed to top last year’s marquee lineup — which included Red Hot Chili Peppers, Tom Petty & The Heartbreakers, and Vampire Weekend, among others — with an equally impressive crop of heavy hitters for 2014. If you care to rock out with the Foo Fighters, Outkast, Imagine Dragons, Pretty Lights, The Lumineers, and Jack Johnson, this is the show for you. Besides, this is probably the only opportunity you’ll ever get to camp out under the stars in the Delaware woodlands. Firefly runs June 12-22, so mark your calendars.
