What Was The Best Concert Of 2012? [POLL]

The year 2012 was filled with tons of kick ass shows. In any situation and all types of weather dozens of rock banks flocked to the Capital Region to put on awesome, fan-filled performances. Among my favorites had to be Lamb of God, As I Lay Dying, Mayhem Fest and of course Q-Ruption. Which was your favorite? Can you pick just one?
