You have to put it in context. We as Europeans have seen these bands time, after time, after time. You as an American want to see those bands and would be ecstatic if you could go to a festival with such a billing. I understand what you are saying, but for us in Europe the situation is completely different.
We are a bunch of spoiled brats.
And you guys are seriously missing out.
O and btw; what are a "bunch of good bands on that bill" is completely subjective and open to personal interpetation and choice.
