Avenged Sevenfold and Good Charlotte co-headline a rock concert at the Freedom Mortgage Pavilion on the Camden Waterfront, pairing a heavy metal headliner with a pop-punk/alternative rock mainstay. The outdoor amphitheater’s waterfront setting across from Philadelphia provides a large, high-energy venue for fans of both modern metal and early-2000s pop-punk to see the bands perform back-to-back.
