I just float around from death to black to classics (RIP, RTL, CFH, etc.). Each offers its own different atmosphere to me and if I find I am getting bored then I switch. As for searching and buying I find it easier to purchase death metal because A) more bands, and B) less of the bands suck - why do so many "black metal" bands suck?! I love black metal, though. It's just, harder to find the good ones?
To me, a decent death metal band will do. It doesn't have to blast my brain to bits, as long as it's groovin' and heavy as all fuck I'm happy.
Production is big for me, though. Like metal where all I hear is the damn kick drum and snare blasting me in the face is not cool. I would sign up to go get blown up in Iraq if I wanted to hear that shit. No thanks!
I find that with a good system, proper sub the kick and bass come out regardless (unless it's AJFA, lol). I don't need "help" from the "producer."
