I haven't listened to much metal lately, but I have a long history with it (and I helped start off this post by arguing about the true definition of "Metal", in true intellectually elitist form).
I've noticed more and more that new metal bands are very formulaic, and it reminded me of the late 90s, early 2000s, when there were a lot of "music schools" opening around the country and advertised constantly on the radio. I put it in quotes because it wasn't like a real college or anything, it was a fast-track program for learning how to play mainstream rock/metal. Now, 5-6 years later, the music scene is awash with these kinds of bands, and they all sound the same to me. I'm over-generalizing, I know, but I think someone here has to know what I mean by all this.
Does anyone else notice that trend?
