Slipknot bites the big one. I find the only people who like them arent very adept in music, even if they play an instrument. (I could be wrong)
And besides, any band that carries themselves on freaky makeup or with a mask or some other image is junk anyway, or they'd use music not appearence to make it big. The only excecption I can think of to that is Kiss. They went without there makeup for the entire decade of the 80's.
