Silent disco parties are fun, and occupy an interesting social niche— you are around other people, having a shared experience, BUT you are each wearing headphones and therefore presumably not speaking to one another. Of course, you’ll end up having opportunities to talk before and after, but this guaranteed time isolated-but-together can be a nice bridge for people who experience some degree of social anxiety.

Here in Cambridge, MA, a friend used to host silent disco parties by bringing a small low-power FM transmitter connected to his audio playback device. He’d hand out small FM receivers & headphones, but people could also bring their own (in those days, most portable audio systems included an FM radio receiver).
