The Twitter account @EDMSectrets claims that they have the real and official lineup of Firefly Music Festival 2015. If this is true, it will surely be the festival of the year (again). Headliners include Paul McCartney, The Killers, and Kings of Leon. The poster also includes bands that are already confirmed for the festival: Spoon, Run The Jewels, Elliphant, Empire Of The Sun, Bastille, Chiddy Bang, and Cheerleader. See the leaked poster below.
The official Firefly lineup will be unveiled this week.
