If you haven ’t heard of a silent disco before, it’ s an opportunity for people to dance while listening to their own music through headphones (or for several DJs to play music at once).
There are companies such as silentevents.com that rent everything you need to run a silent disco, so setting up doesn’t need to be difficult. Because there’s no noise, the disco can be held almost anywhere that there ’ s enough space. Popular with teenagers particularly!
