Tomorrowland concert-goers just outside Barcelona, Spain had to evacuate on Saturday night after fire consumed one of the stages.
Just over 22,000 fans were forced to leave, though no injuries were reported.
Video of the blaze shows smoke billowing from part of the stage as fans seem to calmly leave the area. Several even hang around to take a photo or two.
Event organizers wrote on Facebook that the fire was caused by a “technical problem,” but called the evacuation “fast and professional.”
“Authorities will follow up and continue the investigation with the local Spanish organizer of UNITE,” read a statement on the concert’s website.
