As the festival does each year, Tomorrowland is set to bring the festival attendees in Belgium a lineup of the biggest names in dance music. Not only is its bill of performing artists unrivaled, its incredible aesthetic is as well, providing beautifully wondrous festival grounds accompanied by the year's theme. Following "The Key to Happiness" in 2014, Tomorrowland has announced the 2015 installment of the festival's theme. "Melodia" is a secret kingdom, discovered by a group of children in the video above. You can certainly expect the festival to take its one-of-a-kind experience to the next level with this new theme. Tomorrowland will be taking place July 24 - 26. Grab tickets via the official Tomorrowland website.
