There's a band called Tummy Talk who became a big deal after a video they made on YouTube went viral. In the video, three band members play "drums" on a guy who looks like a sumo wrestler. And all the 'music' is from them slapping the guy's stomach, cheeks, and other body parts. The video has over three million views.

It kind of reminds me of a Blue Man Group type deal... obviously minus the Blue paint and add the big guy.
