+1 to anyone who mentioned Dragon Force. Saw them in concert and it was one of the best shows of my life. Also any band that can do metal without a vocalist that sounds like cookie monster usually will get my vote.
Ummm...I think myself to be a true metalhead....
Metal has evolved over the years...
Blue Cheer
King Crimson
Iron Maiden
Black Sabbath/Ozzy Ozbourne
Metallica
Megadeath
Slayer
Testament
Anthrax
Overkill
Metal Church
Death Angel...
All are excellent examples
Try out:
Candlemass
Sepultura
Overkill
Biohazard
Krux
Massacre
Death
Cannibal Corpse
Capital Punishment
All of which scrape the top of speed, doom, death, thrash, heavy metals...With so much more to be offered when you dig deeper..
My favorites?
Candlemass
Slayer
Pantera
Testament
Overkill
Iron Maiden
Type O Negative
King Diamond
Metallica (pre And Justice for All, everything after...not so good)
Motorhead
Megadeath
King Crimson
Anthrax
in that order (subject to change upon whim)
