How many times does this have to be discussed?

This is a new venue, so chances are it is the venue which is making a shitload of money here, not the band. Also, try comparing even these ticket prices to other high profile artists like Madonna or The Stones and then call them expensive. These are a series of shows to open a new arena, they are events, not part of a tour, so ticket prices areb't representitive of what the regular tour prices will be. Also, comparing ticket prices to what they paid 25 years ago is ridiculous. It's like walking into a car salesroom and asking to buy a car for £50 because that's how much they cost 80 years ago.

Oh, and not to mention that no-one forces anyone to go to a concert.

Let it go.
