I might be way off here, but some of this is promoters and artists going for bigger and bigger arenas to fill demand (and egos I suppose). But if the demand is there - the demand is there. And to be fair it’s probably also matching the changing tastes of people.
We joke about people standing in clubs, but for the likes of Black Coffee and Keinemusik and probably some of the other EDM guys an arena is perfect. People have their own seat / space to film, not get pushed about and can have a seat when they need a quick nap / rest. And people will pay £250+ for a seat in the lower tiers - it’s a fact.
I think I said it’s before, someone in Ibiza is missing a trick with this one!
