The main stage at Ottawa Bluesfest collapsed Sunday night while Cheap Trick were performing.
An unexpected thunderstorm picked up around 8 p.m. EDT, causing the stage to collapse in on itself. The members of Cheap Trick were unharmed, but AP reports that eight people were injured.
Ottawa Bluesfest is one of the largest North American festivals and it’s extremely lucky that more people weren’t hurt.
