Death Core is widely loved and loathed in the metal "society".
The elitists against the other elitists telling the OTHER elitists that they are scene/pussy/faggot/etc.
Musically wise I would define it as a cross between U.S. derived Death Metal;
(Deicide,Cannibal Corpse,Suffocation,Death,Atheist,and the rest of the early Florida death metal staples.)
and Metal Core;
(Darkest hour,Nodes Of Ranvier,Parkway Drive,Sea Of Treachery,etc.)
But as far as lyricism i would have to say there are multiple
bands deriving from hardcore song subjects, done more fragmented than your original Hardcore writer, but the connections are found just the same.
I would also like to put in my two bit and express that the "SCENE" scene will die out in three years give or take,
and by that time, the posers and fakes will show who they really are and own up to their "trend".
so in the mean time,chill out and quit being so hostile towards a trend that will either die out, or evolve into something else.
Death Core bands include,as listed a million times before my post.
(Carnifex,Knights of the abyss,Suicide Silence,
Ion Dissonance,Rose Funeral, Salt the Wound,
Brother Von Doom.)
