Bracket season is upon us and it's time to shoot your shot as we attempt to name the greatest rock band of all-time in this tournament. There are some supreme rock icons with legends such Metallica, AC/DC, Five Finger Death Punch and Nirvana heading up the four corners of the first round pairings. But it won't be easy for any of these acts to advance as System of a Down, Slipknot, Beastie Boys and Papa Roach attempt to pull the upsets. Will The Prince of Darkness, Ozzy Osbourne, be this tournament's Cinderella? Will Smashing Pumpkins smash your bracket? Will Stone Temple Pilots navigate their way through this tough tourney field? It's all up to you to help decide a winner.
