Fans of the band Chicago at Summerfest were in for an unpleasant surprise this year. The band’s founder, Robert Lamm, did not perform at the festival, as he was taken to hospital. Lamm, the band’s keyboard player, was whisked away to Wilwaukee’s Aurora Mount Sinai hospital. He had experienced vertigo and an ambulance was called for him.

At around 10 p.m., the band’s official Facebook page posted a brief message updating its followers on the situation. It stated that, after some examination and a few MRI scans, the doctors found that Lamm suffered from an infection of the inner ear. 

The post also thanked people for their words of support. Additionally, it said that Lamm was doing well and felt eager to rejoin the band as soon as possible. Over 800 people expressed their concern and solidarity with the ill musician.

The band, scheduled to play on June 29, carried on with the show without Lamm. Jon M. Gilbertson, a reviewer for Journal Sentinel, attended the performance and felt pleased with how the band played.
