Severe thunderstorms halted numerous outdoor events this weekend, including Lollapalooza and the Netherlands' Dicky Woodstock 2012.
Lollapalooza was evacuated Saturday after severe storms descended upon the Chicago area.
Tens of thousands of people were told to leave Grant Park about an hour before the storms, and were instructed to seek shelter in underground parking garages designated for emergency evacuations.
The evacuation caused "mass chaos," one concert-goer tweeted. Another twitter user nicknamed the storm "lollapocalypse."
The festival was shut down for just under three hours. No injuries were reported as a result of the storms.
Dicky Woodstock 2012 may have been even more chaotic as a tent collapsed during severe thunderstorms Aug. 4, injuring 13 people and sending attendees running for cover.
11 of the injured people have been released.
A video posted by YouTube user i2Them2 captures the severity of the storms.
