Wow! To many, this is considered a dream matchup for the final round of our Greatest Metal Frontman tournament. Ronnie James Dio and Rob Halford are the last of the 32 men standing and only one of them can be crowned champion.

The late Ronnie James Dio is often regarded as the quintessential voice of metal whether it was his work with the proto-metal band Rainbow, replacing Ozzy Osbourne in Black Sabbath, or pursuing his own ventures with his band Dio. Until the very end of his legendary life, Dio's voice was among the greatest ever in metal. His fans moved him past Iron Maiden's Bruce Dickinson in the semifinals with just under 51 percent of the votes. Dio's other triumphs came over Corey Taylor, Marilyn Manson and King Diamond.

Rob Halford of Judas Priest, one of metal's most dynamic singers with a massive vocal range, is truly deserving of his spot in the final round. A victory over Metallica's James Hetfield with 54.65 percent in the semifinals led him to this championship battle. The Metal God also defeated Till Lindemann, Tom Araya and Bobby Blitz to get here, but he has a huge obstacle in the way in the final round as he takes on another one of metal's greatest voices.

Ronnie James Dio or Rob Halford? Your votes will decide who will be crowned the Greatest Metal Frontman. Voting for this round closes on Tuesday, Nov. 26 at 10AM ET. Fans can vote once per hour, so keep coming back to make sure that your favorite metal musician wins!
