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!

The Sweet 16 round of the MTV Musical March Madness tournament is nearly complete, and many of the eight match-ups currently going down have razor-thin margins between the thrill of victory and the agony of defeat. There are a lot of huge bands -- including Muse, Paramore and defending champs Coheed and Cambria -- on the verge of elimination, but it's not too late to make a late surge and vote for your favorite band to advance to the Elite Eight (which will be announced on Wednesday, March 30).

Voting for all Sweet 16 match-ups will close on Tuesday, March 29 at midnight. As always, you can follow all the voting here.
