It's been five years of Firefly Music Festival and the powerhouse Delaware event shows no signs of slowing its roll. As always, the fest (which is one of the biggest on the East Coast) brought amazing tunes to the woods of Dover, from the likes of Mumford & Sons, deadmau5, Kings of Leon, Florence + The Machine, Blink 182, Major Lazer, and many more huge music names, this past weekend. Attendees came to party and dance, and that's exactly what they did.
