No matter how many concerts or shows you have been to, I guarantee you have never seen anything like the Underwater Music Festival. The Underwater Music Festival is a musical event held yearly by ocean conservationists in the waters of the Florida Keys National Marine Sanctuary.
The 2011 Underwater Music Festival attracted 500 snorkelers and divers, some of who were dressed up in funky costumes and played instruments designed to look like sea creatures. Of course the music played by the "performers" at the festival could not actually be heard, which is why special speakers were dropped into the water to pump out actual tunes. Check out the video here to see the Underwater Music Festival in full swing. The instrumentals for "Under the Sea" really help to pull the whole thing together.
