Dude Hijacks Open-Mic Night For Some Death Metal A capella

Say what you want about metal, it takes talent. Imagine, getting up on stage night after night for a little light growling. If done correctly, it makes no difference to your vocal cords. You'll be good to go for life with no side-effects. Do it poorly, and you'll be having your nodes removed in record time.

Anyway, if you get the chance to hijack an open-mic night, do this and send video.
