A concert will be held at the site of the former OT Johnson store in downtown Galesburg — a sign of what the show’s organizer says is a hope of things to come. After a test run last year, the Downtown Community Partnership will host what it’s calling another “pop-up concert” at the site Friday starting at 5:00 p.m., featuring two “eclectic bands.” Admission is $5; and while alcohol will be for sale along with snacks, it’s described as an all-ages show.
