Metal Madness: Final Four

March Metal Madness started over two weeks ago, with 32 of metal's biggest bands facing off in violent confrontations to claim ultimate supremacy. Having started with 32, we're now down to four.

The Devil Horn Region hosted some incredibly intense battles, with the regional final consisting of Black Sabbath's 'Paranoid' facing off against Slayer's 'Raining Blood.' In a triumphant victory for thrash, Slayer managed to claim victory over the architects of metal known as Black Sabbath.

The Moshpit Region came down to Australian hard rock legends AC/DC with 'Back in Black' going head-to-head with British heavy metal masters Iron Maiden and the epic 'Hallowed Be Thy Name.' The beast was obviously on the side of Maiden during March Metal Madness, as Iron Maiden defeated AC/DC in the finals.

Onto the Headbanger Region -- the final act showcased 'Big 4' leaders Metallica with 'Master of Puppets' vs. Pantera's 'Walk.' Although Pantera fans came out in force, Metallica pulled out another victory; moving onto our Final Four.

Finally, we have the Stage Dive Region. Judas Priest and 'Painkiller,' came up against Motorhead and 'Ace of Spades.' In perhaps the most surprising victory yet, Motorhead killed the metal gods, bringing 'Ace of Spades' into the Final Four.

So here you have it -- the Final Four of March Metal Madness. Vote for which band you want to see in the finals in the poll below. Voting in the Final Four ends at 11:59 PM on Sunday, April 1.
