Half of the Big 4 are clashing in the Quarterfinals of the Metal Madness tournament! Megadeth and Slayer are the two Devil Horn Region representatives and only one will advance to the Semifinals in hopes of being crowned the Best Debut Metal Album of All Time!

Megadeth's Killing Is My Business... And Business Is Good! has been wreaking havoc in this tournament, first eliminating Mayhem's De Mysteriis Dom Sathanas with 82 percent of the votes, and then enjoying another easy run against Mastodon's Remission, coming away with just under 77 percent of the votes.

Slayer's Show No Mercy has knocked off two of death metal's finest debuts. First it was Morbid Angel's Altars of Madness that met the axe and in Round 2, Death's Scream Bloody Gore was the next to fall. In that round, Slayer took home the most metal amount of votes ever — 66.66 percent!

So which album will move on to the Semifinals of Metal Madness 2017? Vote below for either Megadeth's Killing Is My Business... And Business Is Good! or Slayer's Show No Mercy as the Best Debut Metal Album of all time in the poll below!

(This poll will end on Monday, March 27, at 10AM ET. Fans are able to vote once per hour, so keep coming back to make sure your favorite debut album wins!)
