Look what we've got here! Maynard James Keenan represents one of metal's most progressive bands, while Lemmy Kilmister is at the helm of the most unwavering, "if it ain't broke, don't fix it' bands.

Tool fans have been supporting their favorite band throughout our entire tournament the last couple of months and there is no exception here, with each member of the band advancing far into their respective brackets. Maynard James Keenan defeated Peter Steele of Type O Negative with 63 percent of the votes. He faces a tough opponent here against one of metal's most cherished figures.

In a battle of two frontmen notorious for their rock 'n' roll lifestyle, Lemmy Kilmister defeated Ministry mastermind Al Jourgensen handily. Lemmy is known to fans not just as a metal god, but simply 'God.' Motorhead are a genre, not just a band and they have carved their own niche with Lemmy's gravelly voice and thunderous bass playing.
