The grid's too far above them, and you occasionally see shots of it
And I can't see any speakers up there. Floor is more likely.

They'll need some pretty beefy monitors, otherwise all you're gonna be able to hear is the main house PA slapping back off the rear wall, which will have a pretty big delay on it by the time it gets back to the stage. And that really puts people off their performance*

*In my more evil sound engineering moods, when I haven't slept and bands have severely pissed me off I've put about 0.2s delay on their monitor mix, 100% wet. They get half a line into a verse and then stop and give the monitor really weird looks. Best part is you can get the mix sounding awesome sonically, it just makes the band look like talentless idiots.

Not that I'd condone such unprofessional practises. Ahem.
