Tomorrowland takes place in De Schorre National Park in Boom, Belgium, and has been going since 2005. This year is going to be the festival's eighth year, and looks set to be bigger and better than before.
Last year saw a number of events, including 25 airlines organised to being attendees to the festival from all over the world, and the Cloud Rider - which was the highest mobile Ferris wheel in Europe.
Last year sold out in under 45 minutes, so demand is high. Previous performers at the festival have included Moby, Afrojack, David Guetta, Fatboy Slim, Skrillex and Pendulum.
