I'm 17, so I I'm right with all the death-core, crap-core (typo intended), etc lovers. I myself never understood any of if. I'm a huge Black Sabbath fan, I love the old 70's metal, and I like some of the modern stoner rock type things out now. Really I think ever since the early 80's metal has gone down hill into this finally deteriorated genre we know as 'metal'. I have many friends in local metal bands (of the anything-core type) and every single one of them loves Metallica. I won't hate on them because I know a bunch if people here love them, but let's just say I was never a fan, haha.
We have a venue for local bands around where I live, and each time I have the misfortune to go there (when I'm not playing there with my band, which is NOT metal by any means), I'm reminded of the pathetic scene of metal these people have created. In the whole night there might be one band with an actual singer? Otherwise its just some dude up there growling.
Keep in mind this all coming from the only kid in my generation I've met who sits around listening to Yes Peter Gabriel era Genesis, King Crimson, Camel, Gentle Giant, Jethro Tull etc. Needless to say, I've yet to find any drummers/guitarists/vocalists/keys with the same interests, haha. All anyone wants to play around here is...METAL.
