The 44-year-old man, working as a spotlight technician, fell on the right side of the stage around 8:30 p.m., a Miami Fire-Rescue spokesman said. Investigators were trying to figure out why he fell.
A fellow stagehand said the victim was not wearing a safety harness.
The stage crew was devastated, and officials with Clear Channel Entertainment, the show's promoter, issued a statement saying refund or postponement information would be available shortly.
