Human sound system

Get a load of this guy.

[Halo]

Saw a 2-minute documentary sorta thing on him before, what he can do is freaking awesome. In the one I saw, it explained what he meant by using his voice in a way that hasn't been recorded before - essentially, according to traditional study of phonetics, people can only vocally produce one source of sound at a time, whereas he can produce several. Maybe his brain is just wired differently in some way...
