TED Talk: Beardyman demonstrates polyphonic sounds on the Beardytron 5000
 

For those of you not familiar with beardyman, he's a live musician who sources all of his sounds from his voice via beatboxing then mixes all the sounds to create music all completely improvised. In this TED talk he talks about his live process and setup, it's pretty cool stuff.

Here's an older video of a comedy gig he did a few years ago too:
