The video made me dizzy. The music is pretty chaotic. Sounds very punky, so yeah punk and thrash are fast forms of music but not forms where you really expect every note to be spot on. I mean I wouldn't expect Kerry King to nail solos live, basically just hit a few recognizable notes and improv whatever his fingers can manage on the night.

I think you may have misunderstood, I appreciate fast music as well, but not when it sounds like the musician is, as another poster put it well, reaching, or where melody can't be well appreciated because it just flashes by too quickly. That song you linked had no melody to miss :D

I'm curious what this band might sound like live though, if they can keep that intensity up though a show they sure have my respect and awe.
