well the rap sounds a million times better than cookie monster vocals, which i always thought were lame. that band 'Hacktivist' have a grime MC as well, rather than a cheesy hip hop style MC like many of those Nu Metal bands had. I think its original stuff, and pretty good at that.
there was some decent nu metal also, i particularly like Body Count, though not sure if they count as nu metal.. rap metal certainly.
in fact i'd say that this link has shown me, for the first time, some djent i would pay to go see live.
