We've gotten a ton of Q's regarding the song "Don't You Worry Child" by Swedish House Mafia, who are they, are they on tour, where are they from, etc. In short, they're NOT a band, from 3 mixers from Sweden who decided to get together, put out a single, and do some mix-touring. The video of one of their show's (below) is pretty incredible. I'm not sure who else was on the bill, but it looks like a mini Woodstock. Minus the mud, garbage, and the 60's! More on the band...uh I mean mix-trio...from Wikipedia.
