That is insane. He moves his arms like lightning fashion.
That last bit where he attacks his cymbals is impressive, but the thing he does that gets me is how he gradually releases his grip on his left hand into a one-handed drum roll, speeding up his blast to match on everything else. That's technical as all hell. Guy plays like he has separate brains controlling each limb, working together.
I love on the comments on youtube that there's no rhythm and its boring and not impressive. I found this much more enjoyable than most of Neal Peart drum solos and anything else. Its awe-shocking.
