It's MTV's second annual Musical March Madness! MTV News took the 64 biggest names in rock, split them up into four regions, assigned them seeds and puts them up against one another in a single-elimination series of match-ups in a winner-take-all contest. We're leaving it to you to decide an actual champ in this field of 64, so over the next few weeks, fan voting will determine who will emerge as this year's champion. It's all about the fans, and the artist with the most passionate fan base will score the awesome Musical March Madness trophy!
All of the voting in the first round of MTV's Musical March Madness is now open, and you can keep casting your vote for your favorite bands through this Sunday, March 20. We'll reveal all the second round match-ups on Monday, March 21. So far, a handful of familiar faces have jumped out to big leads (including 30 Seconds to Mars, Foo Fighters, Linkin Park and defending champions Coheed and Cambria). Meanwhile, there are excellently close battles happening between Paramore and No Doubt, Arcade Fire and Sum 41 and Patrick Stump and Neon Trees.
