Psychostick. These guys...these guys may seem like goofballs, but their musicianship is top notch. Their drummer Alex is particularly insane.
The way this group matches the instrumentation to their subject matter and vocal delivery is awe inspiring to me. Plus...I find them to be hilarious.
The breakdown at the 2 minute mark is heavier than you'd expect from a Nu Metal band from 2009. It's brutal and packed with energy.
