i don't think that'll flop. they should do some US promo prior like late night shows.
their catalogue is toooooooooooooooo strong for them to flop. word of mouth is going to make them the biggest vegas act after half a year into the game.
they are the best live act ever for a reason. their shows are epic spectacles. the visuals are mindblowing and their songs are evergreens. never forget will destroy their competition.
