Our third battle in the Mosh Pit Region finds one of the "Big 4" squaring off against one of Viking metal's pioneering bands. Which one will advance to Round 2 of the March Metal Madness competition to name the best 21st Century metal album? That's up to you, so let's look at the nominees.

On one side, you've got Anthrax, who went through quite a journey before releasing 2011's 'Worship Music.' The band recorded the disc with frontman Dan Nelson, but eventually made the decision to bring back Joey Belladonna to sing. The end result was one of Anthrax's most vital records in years, with 'Fight 'Em 'Til You Can't' and 'The Devil You Know' generating positive reactions, while 'In the End,' 'I'm Alive' and 'Earth on Hell' added to the depth of this solid release.

On the other side you've got Amon Amarth, who yielded a true gem of an album with 2006's 'With Oden on Our Side.' The band's sixth studio release only strengthened the band's growing legacy and turned out to be their first charting disc on the U.S. Billboard Album Chart. With the heavy, headbanger of a track 'Runes to My Memory,' Jonah Hegg and crew began to establish themselves as a true force. 'Cry of the Blackbirds' was more of a straight-up rocker and it too became a standard for the veteran band.

So will it be Anthrax or Amon Amarth? Vote for either 'Worship Music' or 'With Oden on Our Side' in the March Metal Madness poll below.
