The Firefly Music Festival is quickly turning into one of the premiere summer music destinations. Organizers have revealed the lineup for the second annual event, which includes heavy hitters like the Red Hot Chili Peppers, Tom Petty & the Heartbreakers, Foster the People and more.

As SPIN shares, the roster for the three-day weekend is pretty diverse, ranging from folk revivalists the Lumineers to electro-pop outfits like Passion Pit and MGMT. Other acts on the bill include the Yeah Yeah Yeahs, Vampire Weekend, Kendrick Lamar, Imagine Dragons, Matt and Kim - who have the best "Harlem Shake" video that you can watch below - and a ton more. See the full festival lineup here.

The 2013 Firefly Music Festival takes place June 21-23 at Dover International Speedway in Dover, DE. Early bird three-day passes are $198 and go on sale Wednesday, February 21. Single-day tickets will also be available closer to the festival.

The first ever Firefly Music Festival featured headliners Jack White, the Black Keys, Death Cab For Cutie, the Killers and more than 30 other artists.
