I started seeing videos of his performance I think some time last year and he blew up this year. Not normally big enough for a headline but if they start promoting his sets, and people will see his Sphere shows, it will sell massively. Especially if there is a brand new main stage as I expect. It will essentially sell Sziget as an experience. Much like the Sphere itself that can host him for 8 shows in a row for 500 dollars per sear at a minimum.
If we get something like this at Sziget, but even bigger, flashier, it will sell out:
With zero sign of Chappell doing a solo gig ( and prob staying that way ) then youll get everyone trying their damndest to see her. The only question is how many nw songs will there be/ At this rate theyve already said the new album wont be done next year. So there should be some other new ones in rotation other than what she has been playng. So The Giver will make the cut and what else. 75 mins is plenty of time for her at this juncture anyway.
Oh yeha, and Paramore somewhere in there haha. they sub Neil so its at least a guitar act? Makes sense.
