No I'm not trolling. Am I saying that Cancer and Death (yeah Mantis was a typo) are the same as Suicide Silence and White Chapel, no. But to say that those bands or any Deathcore band for that matter are an evolution from Death and Cancer are wrong. They are not, they are less talented and more generic. I hear people talking about Suicide Silence are so original, no one sounds like them. WRONG. Check out Eternal Suffering from 1994, same sound, same generic riffing, same deep vocals and pig squeals. Eternal Suffering was called Death Metal, not Deathcore. All my ranting diatribe is trying to point out is that A LOT of these bands being labeled slam, or Deathcore, aren't doing anything different from 20 years ago. They are just being called something else. There is no need for that. Anyway, I know a lot of my friends who are all old school death metal guys agree, we hate Deathcore and slam not because of the music, it's because it's all death metal, it should be called death metal. Instead of trying to come up with a suitable "subgenre" just LISTEN to them and see if you like them. There is no need to continously make up new subgenres to place them in to be recognized by people unfamiliar with the basic genres.
I was once told by a dude that Fear Factory was Synth-core and I was like WTF LOL?
Anyway, back to the topic, sorry to intrude. Not trying to be an ass, I am very passionate about DM and I feel all this labeling will soon destroy what it once was. That is why I feel there are so very few stand out bands these days.
Cheers!
