A few thoughts:
- Do power metal bands really draw more in Europe than the US? I think they probably do, but it's probably worth digging up some real numbers and doing the comparison, because I think there is still a tendency for the American mind to imagine these bands playing much larger places than they actually do (and things like Iced Earth putting a picture of Wacken on the back of 'Alive in Athens' certainly fuels this imagination!)
- Do the differences hold up on a population-density basis? Europe generally has a much higher population density than the US, so a single show in Europe may not need to draw from as wide of a geographical area as a show in the US to reach an equivalent number.
- Canada can be a good case-study to test any hypotheses. Again, it would be good to have some real numbers, but my feeling is that power metal bands tend to draw better in Canadian cities than US cities of a similar size. Any valid theory would have to explain this differential, so "bands just do better in their home base" can't be the sole explanation.
- Does Europe (and Canada) have more homogeneity in culture and music tastes than the US? In the US, significant parts of the population devote most of their listening to non-rock genres such as country or hip-hop/R&B. Could this reduce the effective population density of potential power metal fans relative to Europe?
In general, I think a large part of the answer will come down to "who the hell knows why it is like it is?" Figuring out the formula for what makes something popular is the holy grail that the music industry has been eternally trying to discover. The complexity of the system and the number of variables to account for makes predicting the weather look like child's play in comparison, to the point where anything that happens in the music industry can be effectively regarded as random.
Did you take a roll call of all the people there seeing if they liked Blind Guardian??? Just because they were not wearing BG t-shirts how do you know they dont like them????
Holy crap, you
do understand the value of surveying a wider sample space than your two friends! Awesome! I hope that you can now remember that when making your own claims.
I remember a rumor of a Edguy/Brainstorm/Pagan's Mind US tour at one point, I still hope for something that godly again someday
That sounds like a tour of three bands who would want to get paid, and zero who would want to spend money to finance the tour. I really have no idea at what level the "buy-on" line is drawn, but I get the feeling that most tours of this scale need a combination of getting-paid headliners and a paying undercard in order to be financially viable. Most Euro power metal bands are already successful headliners in their own country before coming to the US, so they're likely less interested in touring at a loss. Or splitting the profits with another Euro power metal band headliner. Maybe a Helloween / Gamma Ray tour draws 10% more people at 20% higher ticket prices than either band would get alone, but if they get paid 50% less because they have to split the guarantee, it makes more sense for them to be on their own with "crap" openers instead.
