Wow lots of you people should get to know what metal is.
Just a few bands: Dark Angel, Forbidden, Slayer, Exodus, Razor, MetallicA, Death Angel, Kreator, Sodom, Destruction, Tankard, Coroner, Artillery, Sacred Reich, Wermacht... (note that some of these bands have sold out, so if you want to know what actually is worth listening to, pm me)
Thrash 'till Death!
Also, I hate it when people call Pantera thrash, it ain't. They where glam and then they turned groove "metal"..trendy stuff, not metal.
