AMG Top Thrash Bands (Minus Slayer, Metallica, Anthrax, or Megadeth)

i voted for Sodom. they tend to get overlooked.

The Dirty Rotten 7" came out in 1982, preceding Metallica, Slayer, Overkill, and Mob 47 by a year, at least. "Who Am I" was the first thrash I ever heard. I wouldn't be surprised if Bad Brains or Motorhead recorded songs as fast before DRI, but if so, what were they?
