I haven't the faintest idea. I actually surprised there's not Anthrax in the list?!
Oh, if you want to go there then why is not in the list...
....Coroner, Xentrix, Heathen, Atrophy, Toxik, Znowhite, Darkness, Death Angel, Dark Angel, Sodom, Kreator, Abandoned, Angel Dust (early incarnation), Anacrusis, Flotsam And Jetsam, Forbidden, Hallows Eve, Venom (new), Hellhammer/Celtic Frost (old), etc.
or the near-thrash bands like Abattoir, Exciter, Zoetrope, Suicidal Tendencies, Hirax, Impaler, Meliah Rage, Metal Church, Nasty Savage, S.O.D.
or even those bands I don't dig like Slayer, Overkill, etc.
Well the guy wanted to drew a line, what's wrong with it?
