We hate to say it, but Avicii is already cancelling dates on his last tour of his career.

Avicii was scheduled to perform the next three Sundays at the Encore Beach Club in Las Vegas, but due to “personal reasons,” Avicii has cancelled all performances at the venue. To replace him, Encore has selected Marshmello as a replacement for this Sunday. Other replacements have not yet been specified.

Though not as big as TomorrowWorld, whenever a DJ replaces Avicii on a lineup, they usually go on to do great things. With Marshmello already a considerable rising star, the sky’s the limit from here on out.
