Firefly Music Festival will see its fourth year at The Woodlands of Dover International Speedway in Dover, Delaware – set to take place June 18-21. Many wondered as Firefly entered the festival circuit in 2012 if it would be a success or a flop, but the annual summer affair has proven with each year to posses an even sturdier build than before.

Kings of Leon, The Killers, Morrissey, Snoop Dogg, Foster the People and Zedd are just a handful of names to appear at the 2015 edition of the fest. Steve Aoki, Kygo, The Chainsmokers, Odesza, Tove Lo, Clean Bandit, DJ Mustard, Jayceeoh, Alison Wonderland, Snakehips, Sweater Beats, Solidisco, Vindata, Manilla Killa and The White Panda will hold up the electronic fort of the 119 (and one unannounced) artists on this year’s lineup – more than doubling the genre’s presence in just one year.
