While the horrors of TomorrowWorld (for some people at least) are still very much fresh in people’s minds, their Belgian sister festival Tomorrowland has just announced the release of its full-length documentary This Was Tomorrow. Tomorrowland recently celebrated its 10th anniversary and 2015 marked the first time ever that the festival (and its sister festivals) took place on three continents – North America (TomorrowWorld), South America (Tomorrowland Brasil), and Europe (Tomorrowland).

The film’s world premiere is set for the 26th of November in the Antwerp Sportpaleis and Tomorrowland organizers have promised a truly unforgettable night ahead. Belgium’s National Orchestra will bring the Symphony of Unity, which they’ve only performed once before, containing classic renditions of famous dance anthems by David Guetta, Armin van Buuren, Tiësto, and more.

Tickets will go on sale October 5th at 10 AM, if you’re interested in picking up a few or just more info in general head on over to the official Tomorrowland website for more details.
