I have read a few articles about silent disco in the past but was surprised to learn that it appears to be becoming very popular. According to this article it is becoming popular at weddings and private parties. Silent discos work much the same as regular discos except people dance to music played through personal headphones rather than through speakers. There are several different channels to choose from so people at the same party can choose their own type of music. The article highlights one example where a couple had a silent disco at their wedding reception and chose to have Motown on one channel for older guests and current hits on another for the younger ones. It’s an interesting idea and has the advantage that you can party all night without upsetting the neighbours.
