CHICAGO (AP) – Lollapalooza is returning to Chicago this summer, a year after the coronavirus pandemic forced the cancelation of the music festival that attracts hundreds of thousands of people to a lakefront park. Chicago Mayor Lori Lightfoot’s office said Tuesday that Lollapalooza will return to Grant Park at full capacity July 29-Aug. 1, and the line-up of entertainers will be released at 10 a.m. Wednesday, with tickets going on sale two hours later. People attending the music festival will be required to be fully vaccinated for COVID-19 or have negative COVID-19 test results the day before entry. Organizers said they will detail the festival entry process in early July.
