To see a Big Four show with its lineup of Metallica, Slayer, Megadeth and Anthrax, is to witnessing a masterclass in thrash metal.
But what if it were a Big Five? Who would you add to the lineup?
Anthrax guitarist Scott Ian has an idea. He recently said tat there's only one other band that deserves a place in the elitist thrash school, and that's Exodus.
"The only other band really that it would make sense [to include] as far as American thrash-metal would be Exodus, because they were there right at the beginning as well. Their first album came out right at the same time as the rest of us. So I mean, to me, yes - if you were gonna add a fifth band, certainly I would think Exodus would be able to fill that slot very easily," he told Georgia Straight.
Ian also revealed his personal favorite act from the Big Four:
"If you went into my iTunes and you looked at the play count to see what songs I listen to the most, I would probably bet Slayer gets played more than Metallica or Megadeth."
Their collective live album "The Big Four: Live From Sofia, Bulgaria" went double-platinum this year - though as Blabbermouth note, it helped that the album came with two discs, which meant they only had to sell 50,000 units to pass the 100,000 threshold to claim the double-platinum certification.
