I honestly think our local bands are some of the best in the country. I don't mean huge signed bands (because we have Origin and Manilla Road, your argument is invalid) but local d00ds. Here's some of them:
Sounds like: Grave Digger, Judas Priest, Accept, etc.
Sounds like: Warbringer, early Metallica, early Exodus.
Sounds like: Possessed, Autopsy, old-school DM.
Sounds like: Early Enslaved, Windir, Burzum.
Sounds like: D.R.I., Municipal Waste
Coalesce (this is kind of cheating, but oh well)
Sounds like: Converge, Botch, poser-destroying metalcore.
Sounds like: early Metallica, early Megadeth
Sounds like: Origin, Sepsism, Embryonic Devourment
Sounds like: Cannibal Corpse, Six Feet Under, amazing.
Sounds like: 90's death metal
Sounds like: Decrepit Birth, old Cryptopsy, Origin
