I'm from the UK, I'm pretty sure AOF have a massive fanbase over here which is why they had 2 sell out nights in London for the Farewell Tour and released live CDs from tours here. So I don't see why a band of Marianas' stature in Canada wouldn't find success over here, especially when Josh produced one of the most aired songs of 2012 over here. Which in my opinion is in a similar vein to the singles from Ever After.
Yeah, AOF was big everywhere but the US. I'm just saying whatever, but MT is so huge up here that it's unpractical to tour the US. What are they gonna do, spend a year playing bars and opening concerts and face the chance to not succeeding, or play 2-3 stadium tours a year with all their theatrics up here?
I'm not saying that there isn't an MT audience in Europe or in the US, but at this point of their career, you kinda have to wonder why they'd spend time and money getting "big" when they're already massive here. It's also very expensive acquiring Visas to tour the US. This isn't really an issue for MT at their level, but it explains why a lot of bands from here don't tour the states that often.
