Once again, I don't think those prices are overpriced. I watched the venue from the website and that are a lot of (vip) boxes, special seats etc (ALOT more then I'm used), I assume the higher prices are for those boxes.

Watching a soccermatch in a skybox is more expensiver.

(I do think the normal tickets are normally overpriced - but they have to overprice something as audio as its competeter)
