Fans roared in excitement and organizers sighed with relief as the Tomorrowland music festival kicked off Friday — two days after a massive fire engulfed the main stage and threw one of Europe's biggest summer concert events into doubt.

A day before crowds were set to arrive for the Tomorrowland festival in Belgium, a fire broke out and severely damaged its iconic main stage. The incident occurred in the town of Boom, near Antwerp, just as final preparations were underway.

Video showed thick plumes of black smoke rising from the famed festival grounds in Boom, Belgium on Wednesday. Fireworks could also be seen and heard going off in the distance.
