Sometimes I have a 2 minute conversation with other metal fans on campus or at the mall or something, usually spurred by a shirt Im wearing or a recent tour that came through. Bands I've had people talked about are Megadeth, Napalm Death, Overkill, Metal Church, and the mighty Manowar.
Otherwise I'd say it's pretty nonexistant. And if someone needs to use a copycat band like Trivium to justify metal being alive or "evolving" then they really don't know what the hell they're talking about.
I'd like to throw in another Manowar quote: "It's a shame that future musicians growing up now are being influenced by trash; it's really upsetting. You are basically formed by what your influences are and if you've got losers for influences, you're going to have a hard time overcoming that." -Eric Adams in an interview conducted in 1988
