Would you like something different than a traditional party band on your event? The Danish band Between Music offers AquaSonic: an underwater concert.
Each of the five band members is in a glass cage full of water and plays on self-made instruments. For instance, you can hear a violin and a harp, but they also sing underwater.
In order to realise this AquaSonic, the band members have worked together for years with professional divers and instrument builders. The result sounds rather strange, but if you would like something different, it might be an option.
