Metal is kind of like civilization right now.
The basics don't need to change. What needs to happen is a movement to take over and/or start up something new, now that the old is infested with hipsters, banksters, liberals, scenesters, poseurs, hippies, trustafarians and other useless people.
I mean, look at Krallice. Nice people, clearly know how to play. The music is stupid. Thanks for the inverted chords, but no thanks. At its core, it's just indie rock, the same old shit people have been pumping out sine the 1960s...
We need a movement up out of this rotted carcass infested by Mastodon, Gojira, Chimaira, Necrophagist, Isis, Cannibal Corpse, 0peth, Devin Townsend and other trivial crap.
