Sebastien Leger brought the house down at this 2008's Creamfields in the Czech Republic. And I'm not just using a figure of speech.
"The gig was going really well but the weather was terrible," he recalls. "Suddenly the wind ripped the roof off and then the speakers collapsed almost on top of me. It was a nightmare!" The rest of the event had to be canceled and luckily nobody was injured. Leger and many caught the incident on cameras and the footage is now on YouTube.

Here is a version with better audio from Leger's own camera:
