Any good, underrated metal bands?

Some underrated thrash:

Forbidden - Forbidden Evil and Twisted Into Form
Realm - Suiciety
Atrophy - Socialized Hate and Violent By Nature
Xentrix - Shattered Existence and For Whose Advantage
Vendetta - Brain Damage
Blind Illusion - The Sane Asylum
Demolition Hammer - Tortured Existence
Exhorder - Slaughter In The Vatican
Heathen - Victims Of Deception
Paradox - Heresy
Mortal Sin - Face Of Despair
Sacred Reich - The American Way
Ulyssess Siren - Above The Ashes

That's a good list of thrash to be going on with. There's plenty more but get yer chops into some of that :)
 
Try The Morningside. Prehaps one of my favourite artist of all time, and it is so underrated. Kinda death/doom metal if thats cool with you.
 
deathcore/metalcore nowadays isn't even close to being actual hardcore punk, so avoid it. some good crust bands are:

Warcollapse
Anti-Cimex
Hellbastard
Disrupt
Disclose
Anti-Product
Amebix
Axegrinder
Gloom
Gauze
Personally, I think crust, in general, is underrated.
 
Winds of Plague is the worst Deathcore band I know of, how did you let them be an exception?

Well honestly I've only heard 4 of their songs and thought they were pretty decent. And those were the 30 second samples on iTunes, so I dont know. They sounded decent to me, but I guess you can't judge from that, haha. I'm also a sucker for metal with a keyboard for some reason. But i've never really given them much thought, just thought they sounded decent from a few samples. Probably shouldn't have listed it on there but oh well.
