Protest the Hero, ANYTHING of of Kezia will immediately throw me into mosh mode. While Bloodmeat will also make me want to destroy stuff. I'm also a fan of Assassinate the Following.. local band that's starting to get big and has toured with them! If you listen to them on youtube, you can hear an escapist do a bit of vocals in Just Another Day.
Also, Mogwai, I just imagine killing someone to Mogwai, especially Burn Girl Prom Queen.
