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 fire broke out at the main stage of the Tomorrowland music festival in Belgium. Organizers said they are "finding solutions" for the July 18-20 event.

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.
