"I'm sorry for having to postpone the shows this month," Avicii told fans via Twitter earlier this week. "I sincerely�wish I didn't have to but unfortunately there's no going around it�Health must always come first and in this case especially after my ruptured appendix that got removed doctors orders have been really strict."

Among those canceled dates include a pair of shows at the Encore Beach Club in Las Vegas, where Avicii maintains a DJ residency. While Avicii fans planning on catching him at either of the upcoming dates are sure to be disappointed, two of EDM's biggest names have agreed to step up and rock the decks in his absence.
