There's no ONE elitist metal genre. There are band's that the elistst type gravitate towards in about every genre. These bands are usually more raw, brutal & free of hooks than the more popular metal bands. This doesn't apply to everybody though.
I think ANUS is the best place to go to see what I speak of. If a band starts to tighten their sound or production for an album they immediately write the band off & quit reviewing their work. If a band streamlines their sound many of these so called "elitists" will speak of the band as if they were never metal to begin with.
This is the thought from which my "In Death considered Death Metal" thread originated from. I've heard them all:
* "Death is not death metal"
* "Metallica were never a metal band"
* "Slayer is not metal"
* "Testament are the worst Thrash band that ever existed"
* "Therion's early stuff is much better than their shitty "Gothic Kabbalah" album"
(OK, that's just one that pisses me off)
* "Massacra > Pestilence"
(Yeah fucking right)
Taste is subjective, but all those are elitist arguments I've heard at one time or another by people that looked as if they felt they had something to prove. I think there's a line to draw somewhere.
Well, that's my stance on metal genre elitim in a nutshell. I do agree about Jazz being elitist though. I know some folks that have the whole "jazz = high horse" thing going on & it's just sickening to me. I hear guys go as far to compare Symphony X to jazz

to put down SX because their music is not as technically complex or demanding as jazz. It's fucking sick. Definitely #1 elitist genre. I still like a lot of it, but damn do the poeple who are into it take it too far.
