XPoNential Music Festival 2018
Time Out says
Once again, WXPN has put together a three-day music festival across the river with plenty of big names, old favorites and up-and-comers. I imagine longtime listeners know the top tier talent—The War on Drugs, David Byrne, Preservation Jazz Hall Band, Sylvan Esso, Sturgill Simpson—but you gotta swing by the small stages to see Mt. Joy, Tank and the Bangas, Courtney Marie Andrews, Swift Technique and Hurry.
