"2015 will indeed be the biggest and best UME weekend to date since its inception five years ago," Paul Magee, CEO of Global Groove Events, told Billboard.

"We have three of the biggest heavy-hitters in the world headlining which includes Guetta, Hardwell and Tiësto. Due to an already high ticket demand, we've added an impressive pre-party, also at the Schlitterbahn Beach Waterpark."
