This kind of matchup is what this Greatest Metal Frontman competition is all about. We have two living legends going at it with Bruce Dickinson against Lemmy Kilmister!

Iron Maiden frontman Bruce Dickinson is one of metal's greatest vocalists and live performers, and he showed Megadeth's Dave Mustaine the door in the second round as he collected 67 percent of your votes. His first victory came over System of a Down's Serj Tankian, and he'll certainly need to keep the ball rolling in what might be his toughest matchup yet.

Lemmy managed to stave off a rabid Tool fanbase with a win over Maynard James Keenan, as the veteran rocker scored 55 percent of the votes. The Motorhead mainman had a decisive victory over Ministry's Al Jourgensen in the first round and will need a strong push from Motorhead fans in the quarterfinals to come out ahead against Bruce.
