One of the most powerful rock bands, period. Out of all 80s a-list thrashers, they were probably some of the most angry ones (you certainly don't think that Metallica or Anthrax would get away after writing lyrics about necrophilia, do you?). Not to to say that they were always on point (90s, for the most part, weren't very kind to them), but out of all their mates from the 80s, they probably still stand as some of the most angry and effective ones.
