No, I tend to just not be a classic death metal listener and think that all other genre's suck. I'd also say a band like Maudlin of the Well blows any death metal or black metal band out of the water in creating a creepy or decent atmosphere.
Chimaira isnt "brutal" heavy because of low tuned guitars, they're heavy because Mark Hunter's vocals are aggressive, they're heavy because their music conveys it, and they're heavy because they dont have to rely on telling demon folklore to create any sort of mood.
Chimaira was never nu metal to start with. Limp Bizkit or what the hell ever is nu metal, Korn is nu metal, Chimaira is not. Its amazing what time you hit the scene can have you thrown in to. SOAD is a nice example. why the hell they ever got the nu metal label was always beyond me also.
