After the spectacular year Tomorrowland has had, this film is coming at the perfect time.

With stunning editions in Belgium, Brazil and Atlanta as TomorrowWorld (though this was slightly marred by mishaps), Tomorrowland has built its own empire this year. With magnificent stages and brilliant performances by the best artists in the biz, nearly everything has gone right for the festival in 2015.

Steve Angelo Mako’s collaborative single “Children Of The Wild” is the backdrop to this awesome first trailer of the feature film documentary, that’s all set to release on December 1. With gorgeous footage of the different editions of Tomorrowland, the trailer manages to capture just how epic it was. It also speaks about the dawn of the era of EDM, and how music has united all kinds of people from every part of the world.
