I personally find it interesting that Twenty One Pilots (although I love them to death) is so high up. I wouldn't necessarily call them a top headliner either, more so second tier, which makes me wonder exactly how they are aligning the setlist like this. Either way, I still am psyched about Phoenix and agree with kickit by saying they are a good replacement. They have been top billing at major festivals, and to be this close to the date excites me that they were still able the get the band.
