According to this article, U.S. bands on international tours are getting richer thanks to a weak-ass dollar:
"If there is any net profit from foreign touring, in some cases the profit is 20%-40% higher than it was budgeted based on nothing more than currency exchange," Zysblat says. "Not selling more tickets. Not increasing ticket prices. Just the shift in the U.S. dollar."
Bottom line, this should mean more international touring next year by American bands. That said, the reverse could also be true. "I see fewer U.S. dates by foreign bands," Zysblat says. "Their time is better spent elsewhere."
I think alt-country is big in Europe still, so get over there while the gettin's good.
