Even though this video is basically called "Human Beatbox vs drummer" it really isn't a "vs" match nor there isn't really a battle.
Watch the beginning to get an idea of the drummer's tricks, then fast forward to ~5:48 to see something really awesome!

I love how relaxed he seems the whole time. I thought his playing was really good the whole time, but the ending was definitely the most impressive.
