Round 3! Vote for the Best Band of the '70s, '80s, '90s and '00s (March Madness)

It's time to vote in Round 3 of Loudwire's March Madness: Decades of Destruction tournament! Just eight bands remains in the final matchups within each of the four divisions.

It'll be Black Sabbath Vs. Queen, Ozzy Osbourne Vs. Metallica, Pantera Vs. Nirvana and Slipknot Vs. System of a Down and your votes will narrow it down to the Final Four with one representative from four difference decades.

In Round 2, the closest matchup we saw was between Nirvana and Korn, with the grunge groundbreakers edging out the nu-metal pioneers by less than five percent of the votes. The biggest landslide? That goes to Metallica, who triumphed over Guns N' Roses with a shocking 81 percent of the votes.

The polls are back open and we've got another round of fierce matchups that will force you to make some difficult decisions.
