Chugging, brutal riffs. Cookie monster vocals. Swedish and Scandinavian bands like Children of Bodom..... Pointy guitars, hung really low, almost to the knees. The entire band either looks like professional wrestlers or looks like the guys that get beat up by professional wrestlers....is that what you are talking about?
If so, I have heard them. Like rap music, it's music for kids trying real hard to sound tough and scary. The subject matter and lyrics sound like the kind of stuff we use to scribble in our notebooks while bored in the classroom, when we were 13 years old and first trying drugs.
Sorry, I would rather listen to Frank Sinatra. or Rush.
And just so you know, metal has not changed that much since the days of Priest and Sabbath. It just got faster, more rythmic. The use of minor keys, modified blues scales, pentatonic scales are all still there. The difference is that the original heavy metal bands pretty much came up with this stuff on their own, so in a sense, it was very original. The new stuff is based on what you heard your older brothers or dads listen to, throw in some thrash and punk elements, and you got modern day metal.
And what always cracks me up is when a metal head like you tries to sit in with a real musical band, and tries to fit those same riffs and scales into an actual song. it never works, and ends up sounding bush league.
Metal heads are completely unaware of what a guitar is supposed to sound like. You think it comes out of the womb already distorted and loud.
What you guys with your metal do is deeply restricted only to your favorite genre of music, and can rarely be used anywhere else.
I will go you one further and say that you can quickly train a jazz or classical musician to learn your riffs, probably within a week. heck, I know musicians that could sight read any one of your "shredding" solos, even on a violin.
But try and step in their world, and see how hard jazz and classical music is compared to what you do.
yeah, I know what modern metal is. I don't like it, but that does not mean I am unaware of what it sounds like. Ever heard of youtube?
