Slipknot? I don't like bands like that that are all image.

I recommend: System of a Down, Red Hot Chili Peppers, Franz Ferdinand, Muse, Rammstein, Linkin Park, Jet, The Killers, CKY, The Datsuns, Foo Fighters, The Hives, Placebo, Queens of the Stone Age, The White Stripes, Rage Against the Machine, REM, The Strokes.

All very good.
