Loudwire's March Metal Madness 2013 continues to search for metal's all-time greatest album with yet another battle of epic proportions. We're down to the final four, and this pairing places together two metal masterpieces from the early '90s.

Megadeth have kept their momentum going throughout the entire competition, most recently defeating Slayer's 'Reign in Blood' album with a monumental victory. Now, Megadeth's 'Rust in Peace' has advanced to the semifinals to face a group of progressive metal masters.

Just like the NCAA has Wichita State in its Final Four this year, March Metal Madness has a Cinderella story of its own with Dream Theater's 'Images and Words.' The progressive metal band has taken down giants during their run, most recently an incredible win over Judas Priest's 'Screaming for Vengeance.' But can Dream Theater defeat the mighty Megadeth?
