B-B-B-Beat Box

Actually, this isn't beat boxing. This is far more advanced. Like an alien race or something.

I saw this guy on TV yesterday. They said his snare/hi-hat/snare/hi-hat sound is so fast (18 times a second) that if he did it any faster our ears could only hear it as a constant sound with no distinction.

He's in a room with cool acoustics, but he's making all of the echo sounds himself.  Enjoy!
