I dont see any market where Maiden is selling more tickets. Metallica is doing mostly stadium and open air shows last few years.
OK, but Iron Maiden are playing more concerts (generally), and you must realize Metallica doubled the shows with 80% the same people in the audience both nights! This could be called a monopolization strategy in the concert markets (money-grabbing anyway). The final results are fewer shows, more big venues, and more people, just because of their strategy to sell two shows at the same stadium(s) to the same people and even give them "free CDs".I dont see any market where Maiden is selling more tickets.
