But by that point Cheap Trick had already left the stage because they'd seen a
large group of black clouds coming into the area, according to CBC News.
"A giant gust of wind picked up a tarp and garbage from across the field and flung it towards the audience and lifted the whole stage — where Cheap Trick had been playing — and almost like a convertible in a car, just folded it backwards in the same direction," CBC's Stuart Mills said.
According to Cheap Trick’s website: “Severe weather hit the stage as Cheap Trick was performing at the Ottawa Bluesfest tonight. The stage blew down and collapsed. Everyone is shaken up but band and crew are all fine. Cheap Trick hopes that everyone who attended the show is also okay. Robin says ‘Fortunately the band and crew are all lucky to be alive and we’ll see you down the road. And all the best to our truck driver Sandy.’"
The band’s manager, Dave Frey explained to a reporter at CNN that “one of our drivers will spend the night in the hospital, and though we’re not sure how, Cheap Trick are grateful and happy to say that everyone, including all the concert goers, are okay.”
After the stage collapsed, thousands of fans were made to evacuate from LeBreton Flats, the festival site, and the rest of the bands were canceled, including performances by Joe Satriani and Death Cab for Cutie. Death Cab’s Ben Gibbard tweeted, “We are all okay. Band, crew, and drivers,” then “It was a miracle no one was killed today when the stage collapsed. Gear can be replaced, people can’t.” Two hours later he promised: “We will return to Ottawa and play a proper show as soon as our schedule permits.”
