Three days of partying in Houthalen-Helchteren (Belgium) with every kind of house and techno is an extremely good idea. With seven ‘districts’ to build and more than 120 top performers Extrema Outdoor is among the hottest festivals to launch the summer with. Coreworks festival structures are right at home here: a well-oiled mainstage, ditto entrance structure, seven kicking event stages and more than twenty towers, spread over the areas, activations and campsite. Throw in some dance decks, FOHs and a core-a-sol and you’ll be very close to creating the best XO edition ever.
