So here's a video of me playing the introduction to System of a Down's "Atwa." I start singing the actual song but eventually veer off course and hit a tree or some other immovable object. Check it, son!

(note: I mess up on the lyrics, so don't lynch me there. And, I'm not good at singing, let alone singing and playing simultaneously)
 

Mmmm..... saaaand......wich.
