The Big 4 of thrash metal are Metallica, Slayer, Megadeth and Anthrax. We know this. It's written into metal history in permanent marker, rubber-stamped for good measure. Yes, you want to make your case for Testament or Exodus or whoever, but entries are closed. It's a done deal.
But what if we opened that concept up to all of metal? Who would be the Big 4 for the entire genre, is what I'm asking. Metallica have to still go in, obviously. They're the biggest metal band in history and one of the most influential. Plus, I'm not arguing with anyone who wants to label Master Of Puppets as the greatest metal album ever. To me, Metallica is a no-brainer.
