'The XPoNential Music Festival offers an unparalleled experience for music discovery. With a lineup of established and up-and-coming artists heard on WXPN 88.5FM, the award-winning Philadelphia public radio station, along with a variety of family-friendly activities, the XPoNential Music Festival has been pleasing audiences of all ages for more than a decade on the Camden Waterfront.' WXPN and the Camden County Board of Commissioners present the XPoNential Music Festival presented by Subaru. The festival returns to the Camden Waterfront on September 16, 17, and 18. As always, our Festival is a great opportunity to see established artists and to discover new up-and-coming bands.
