"It's Musical March Madness! The sprawling bracket — both a parody and a tribute to the NCAA basketball tournament, masterminded by MTV News' James Montgomery — takes the 65 biggest names in rock, splits them up into four regions, assigns 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 65. Over the next few weeks, we will present a series of polls that will allow you to vote for the match-ups presented in MTV News' Band Bracketology. You vote for the winners, we'll keep advancing the seeds and, in the end, we'll have some sort of champion. What will the winner receive? Little more than our esteem (as well as that of the fans) and some Internet bragging rights.

It's the final day of the opening round, and while the polls are still open on a handful of the other races, today's match-ups focus on the South region — perhaps the toughest in the entire tournament. Top-seeded Kings of Leon are a powerhouse, for sure, but can they survive the onslaught from the rest of the pack? Let's take a look at the first two pairings of the day."
