Nope, its just "Book the Band" winners Hollywood Undead. Their angry, shouting rap/ rock confection was reverberating through the stands, a reminder of last summer's similar Beastie set.

But hey guys, what's up with the masks? Each of them had a very distinct and frightening disguise, ranging from a bandit bandana to clown makeup.

While the crowd was pretty much nonexistent (the band was the first band to grace the stage) those who were there weren't hopping around nearly as excitedly as the six members; "Charlie Scene," "Deuce," "J-Dog," "Johnny 3 Tears," "Funny Man" and "Da Kurizz."

They were certainly very energetic, but that wasn't translating to the crowd. Maybe because the bass was unbearable, and drowning out a lot of what I can only assume were the ironic lyrics they are known for.
