These are the Voca People. According to Shai Fishman, they came from a musical planet called Voca, located just between the Ursa minor and Ursa major. Planet Voca is a planet where music is used to communicate.
They have landed here on earth to do some shows, and make the Earthlings realize the beauty of music.
Well, after watching their video, I realized that I haven't appreciated Earth music that enough before.
These aliens are great!
Here's another video of a concert they did in Brazil! For those who'd been saying that their YouTube videos had the sounds modified, check this out.
I soooo love the Bohemian Rhapsody part!
Don't they deserve a standing ovation?
