When you're a chubby guy, there is a point in your life that you will be sitting on the couch and suddenly a beat pops into your head. You start to tap it out on your tummy, finding different areas that make different sounds like a steel drum. You skinny guys wouldn't understand how much we can jam out on our stomachs!
This is kind of like that only WAY MORE AWESOME!
I don't how the guy stood there and took it, but the 3 drummers are getting down on this belly drum!
