We've reached the Quarterfinals of our Best Live Band competition, and we've got two polar opposites fighting head to head. Despite their differences, both acts have helped revolutionize the live concert experience.

In one of the closest decisions we've ever had in a bracket, KISS narrowly beat out Rammstein to advance to the Quarterfinals. After defeating GWAR by a healthy margin, KISS took home 50.51 percent of the vote in their war against Rammstein. Can the explosive rock 'n' roll innovators get past their next challenge?

Tool celebrate their second consecutive win in our tournament with a victory over Motley Crue. Having also defeated Nine Inch Nails in Round 1, Tool are on a roll. With their hallucinogenic live show, which features a stunning LED screen that grows as the show progresses, Tool are certainly innovators in their own right.

So who will advance to the Final Four? Do you like KISS or Tool in this matchup for Best Live Band? You can vote once per hour through the deadline of Tuesday, July 28 at 10AM ET. So make your choice in the poll below and come back to make sure your favorite live act advances.
