ooooooh killians vocals put me off violence for aaaages, until i actually forced myself to sit through it... there is some excellent riffing going on, but the vocals. just, not for me. i can see why they cause such a divide though, why people love them or hate them.
and comparing violence to machine head is pointless, much like a woman having a sex-change only to get pregnant....
machine head were good for the first two albums. burn my eyes and more things change were just good, heavy, metal. since then they've trend hopped like mad and no-one seems to call them on it.
anyway, cyanide is the best track on DM, and it still only gets a 4/10.
