The annual free summer concert series kicks off Friday, July 12 outside the GM Renaissance Center! The six weeks of free Friday night concerts begin July 12 and run through August 16. Rock and roll returns to the Detroit Riverfront this summer for the annual Rockin’ on the Riverfront summer concert series presented by Chevrolet. Once again, the 2013 lineup is sure to satisfy classic rock fans who look forward to this event each year. Admission to the concerts is always free and no tickets are necessary. Viewing space is offered on a first-come, first-served basis. Attendees are encouraged to bring their own lawn chairs and blankets, but outside food, beverages and coolers are not permitted. In addition, boaters on the Detroit River are welcome to anchor near the riverfront and enjoy the shows from the water. Check the website link for the 2013 concert lineup.
