Copper Box returns for our annual Friday night Concert along the picturesque Rock River in Beloit, WI. The series is put on by Friends of Riverfront and features jazz, blues, swing, and big band. Attendees bring their own lawn chairs or blankets and relax under the stars while enjoying the region’s hottest bands! There are also several food truck vendors offering a variety of tasty treats, soft drinks, and beer for those of age.
