You know, i was thinking. Music stopped evolving in the 2000's. Look at the crazy range of variations made in the 90's. Hair metal, thrash, death metal. We also had popular industrial bands. Some bands that didn't fit categories, such as White Zombie. Rapcore. Even rappers starting to act more metal, and metal and rap groups coming together. Near the end hardcore started gaining momentum. And the birth of metalcore. Even some goth bands got more popular. Or even Red Hot Chili Peppers. The introduction of black metal. Grunge made an appearance. Pop punk. Ska.
What real variations do we see in the 2000's? We saw metalcore go from being defined by bands like Zao to bands like Killswitch Engage.
I mean, we may have some variations in subgeneres, like black metal spawning folk/viking/pagan/funeral, etc.. but really, those are just tweeks of one key style.
And yes, i know not all those styles started in the 90's, but those were all popular styles in the 90's. And some did start in the 90s.
I don't know, seems like the scene has turned into this unevolving, dead parody of itself. No wonder i so often find myself reverting back to that time, musically.
