These guys are sick, specially Dave the frontman. He's a Berkley student and is incredibly smart. This is from their early work and is quite raw. I recommend going into "No Funeral" or "The Grip Tightens" which are a little more polished.
It's like punk thrash metal prog rock fusion jazz. There's even a groovy funk breakdown which sounds like prime Chili Peppers at the end. That's was fantastic in a shocking way!
