Lot's of kids dancing around, enjoying themselves. No city officials trying to enforce the "sound ordinance", and not one bit of plaster falling from the ceiling caused by six 10 foot tall speakers.  As long as people are having fun, whats the harm..

Disco isn’t dead. It just went quiet. Just walk into a Silent Disco event and see for yourself: a couple hundred people, two DJs spinning, and a dance floor filled with gyrating dancers – in total silence.
