The 2011 MTV Musical March Madness tournament is now underway! 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.
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!
