On Friday, Imagine Dragons will headline the T in the Park festival in Scotland. On Saturday, they will rock Major League Baseball's All-Star Concert in Minneapolis.
Who schedules these things? Scotland one night, Minneapolis the next.
"That's not even the beginning of it," Imagine Dragons lead singer Dan Reynold said last week from — where else? — Norway. "First we went to Canada for the Much Music Awards. Then we flew to Hong Kong for the movie premiere ["Transformers: Age of Extinction"] and then we flew straight to Dover, Delaware, for Firefly [Music Festival] and from that we flew to Europe for festivals. I've been in so many different time zones. It's definitely a great problem to have."
It's the problem you have when you're America's biggest rock band of the moment.
In fact, the Las Vegas quartet has pulled off something that perhaps no other act has done before: gone from clubs to stadiums on the strength of its debut album.
"I can't think of anybody else who's done it," said Gary Bongiovanni, editor of Pollstar, the concert journal. "I wouldn't look to Imagine Dragons to tour stadiums following this show. But they are playing lots of big festivals."
Said Reynolds: "I can't wrap my head around it. I don't think any band could dream of what's happened or prepare for it. None of us knew it would move at this pace. It's overwhelming."
The biggest crowd the Imagine Dragons have faced is about 100,000 at the Rock am Ring fest in Germany and Lollapalooza in Brazil. Reynolds can't remember his biggest U.S. audience. "I just see faces as far as the eye can see," he said. "It's a pretty amazing sight."
