WOW! This is quite INTERESTING! Check out this video of music being played UNDER WATER! AquaSonic is an Under Water Concert by a group called Between Music.
Now Music and Water...Even more Blue Mind???!!! :-) Although I will say some of the music seems a bit creepy (just my opinion) and made me think about the under water scenes in Harry Potter: Goblet of Fire and the "Merpeople." HA! :-)
