Primus Mr. Knowitall from Frizzle Fry
Pixies Where is my Mind from Surfer Rosa
Tool The Grudge from Lateralus
My favorite band is actually Psoriasis.

This was tough, it is hard to pick one good song that represents these bands. Primus is awesome live. I also need to give cred to Mr. Bungle and White Stripes.
