Name me some good metalcore/metal/deathcore/hard rock bands...?

Carnifex = phenominal. for other bands like them you should check otu job for a cowboy and suicide silence, also based on the other bands yo've listed you may like bring me the horizon, architects(the uk band) drop dead gorgouse, calliban, parkwaydrive, killwhitneydead, I killed the prom queen are f**king amazing and you shuld also check out misery signals, but out of all that JOB FOR A COWBOY = GODS http://www.youtube.com/watch?v=S-x95Q0SJfY

Caliban, KillWhitneyDead, I Killed the Prom Queen, Parkway Drive, Carpathian, Cattle Decapitation.

Parkway Drive, Unearth, Bury My Sins, 3 Inches of Blood

try Dragonforce, heavy and fast-paced with thick double bass.

I also like Hammerfall, Iced Earth, Kamelot, Nightwish, Epica. Those are starting to lean into the realm of goth-metal or progressive rock but it's still pretty good. Also- try Slipknot, Diecast? Good heavy metal.

Hope that helps.

Stop listening to Emmure and start listening to the Acacia Strain.

trivium, all that remains, killswitch engage, bring me the horizon, bullet for my valentine, static-x

killswitch engage, lollipop lust kill, behemoth, necrophagist, carcass, the bubbles, the faceless, five finger death punch, kill whitney dead, at the gates, whitechappel, suicide silence.
