Rock the Badges Battle of the Bands in Chicago

Members of the Chicago Police Department and Chicago Fire Department will square off on stage today for bragging rights and to raise money for two charities that help the families of fallen officers and firefighters.

Proceeds from the third annual Rock the Badges concert will benefit the Chicago Police Memorial Foundation and Ignite the Spirit, two charities that help the families of officers and firefighters killed in the line of duty.

The first two Rock the Badges events raised $20,000 for the charities, said organizer Chicago Police Lt. John Garrido.

Doors open at 2 p.m., and the opening bands will take the stage at 3 p.m., organizers said. The competition will take place from 5-10 p.m. outside at the Copernicus Center, 5216 W. Lawrence Ave.
