In this quarterfinals matchup in our quest to find the ultimate live act, we've got two concert giants about to go into battle. Both can fill arenas, but which group's fans will take them to the next stage?

In a battle of American titans, Slipknot prevailed over Metallica by a very narrow margin: 50.74 percent of the overall vote. Along with a Round 1 win over the Dillinger Escape Plan in Round 1, the masked nine have proven they're one of the most respected bands on the concert circuit.

Avenged Sevenfold have some insane fans to say the least, but they couldn't compare with the followers of X Japan. The Japanese veterans accumulated over 70 percent of the vote in their battle vs. A7X, having also previously beaten modern heavyweights Linkin Park.

So who will advance to the Final Four? Do you like Slipknot or X Japan in this matchup for Best Live Band? You can vote once per hour through the deadline of Tuesday, July 28 at 10AM ET. So make your choice in the poll below and come back to make sure your favorite live act advances.
