The Lumineers, Dr. Dog and Polica will perform at the 20th annual the XPoNential Music Festival this summer. Sponsored by radio station WXPN, the multi-stage festival will take place in Camden, NJ from July 26-28. All three of the festival’s confirmed acts will perform at Camden, NJ’s The Susquehanna Bank Center. Fans who purchase tickets to the XPoNential Music Festival will receive lawn tickets for that portion of the weekend-long event. (Like last year, you do not need an “XPoNentiatol attend The Susquehanna Bank Center part of the festival.) XPoNential’s other acts will be confirmed in the coming weeks.

The Lumineers confirmed marquee spots at both Mountain Jam and the new Shaky Knees Fest yesterday. The Americana group is up for a Grammy and recently scored their first appearance on SNL.
