Pearl Jam's next album is called "Lightning Bolt." Perhaps Mother Nature took it too literally.
The good times were interrupted at the band's Wrigley Field concert due to the weather.
Officials halted the concert shortly before 9 p.m. because of the threat of lightning.
Lead singer Eddie Vedder informed the crowd of the delay and assured them they would be able to play past the curfew when they do get back on stage.
Fans were cleared from the field into sheltered areas and some left the stadium. They were originally told the delay would last around an hour.
A tweet from Pearl Jam's official account shortly before 11 p.m. said they were waiting for a second cell of rain to pass before continuing the show, and that they intended to provide fans with a full show.
A fan inside the stadium said people were starting to move back toward their seats at 11:30 p.m.
The Pitchfork Music Festival at Union Park in the West Loop ended a little earlier than planned because of the rain.
And Phish fans were left scrambling from the rain during that show at Charter One Pavilion at Northerly Island.
A Severe Thunderstorm Warning was in effect for Cook and DuPage counties until 10 p.m. but significant rain was still reported throughout the viewing area well after that.
