For me, aside from ass-kicking riffs and double blasts, the most important thing in metal is a good vocalist. I can forgive some bands that have all-cookie monster vocals, like Chimaira, for example, because it complements their shit pretty well, but if they're gonna do melodic, they better do it right. I can't really stand the maidenesque high pitched vocals. Five Finger Death Punch is a pretty good example for the kind of vocal mixups that I like.
Thanks for all the great ideas, guys, I will definitely check out Darkane and Dillinger Escape Plan (I'm a huge FNM fan, I have no clue how I've never gotten into them).
Everyone of you should check out
Textures, they're described as a math/death/melodic metal band from Holland and they're the latest modern band that is kicking my ass all over the place.
Can someone tell me what's so bad about Avenged Sevenfold? In a genre so full of rip-offs, at least they're mixing their influences pretty well. I probably didn't get exposed to them as much, since I don't live in the states, but I think their metal stands out from the rest (kindergarten lyrics notwithstanding on their latest album).
