Weather played havoc with at least three of the major outdoor music shows in Chicago Friday night.
After Pearl Jam performed seven songs Friday at Wrigley Field, singer Eddie Vedder announced that heavy weather was on its way and the concert would be delayed.
Fans on the infield exited to shelter beneath the grandstand before the storm moved in about an hour later.
Pearl Jam tweets that they're waiting out a second weather system. "Intend to provide full show" at Wrigley.
The storm also caused Bjork to cut short her headlining appearance at the Pitchfork festival in Union Park, and the first of Phish's three concerts at Northerly Island was evacuated just before 9:30 p.m.
