Last night's event finished approximately two hours earlier than planned.
Dixon and Job Jobse were playing a seven-hour back-to-back in the city's historic space when debris began falling from the roof, RTL Nieuws reports. The promoter, Audio Obscura, evacuated approximately 1,000 visitors at 1 AM, two hours before the event was due to finish. According to the venue, the damaged section of the ceiling has been removed and all scheduled performances will take place as planned. It is not yet clear whether the event itself caused the damage, though lasers and speakers had been attached to the roof.
The Concertgebouw posted this statement on Facebook this morning, which we translated from Dutch.
"Last night during a dance event in the Concertgebouw we found that grit had come loose from a plaster moulding above the stage in the Great Hall. We decided to end the event prematurely due to the safety of the visitors. The house is now clear. An inspection found that a small part of the stucco is damaged; this section has now been removed. No one is in danger. It is being examined whether the damage is related to the event. The Concertgebouw hosts dance events a couple of times a year because we wish it to be accessible to as many people as possible. All upcoming concerts and rehearsals will continue."
