Building on to the exciting Saturday-night XPoNential Music Festival roster at Susquehanna Bank Center with St. Vincent and My Morning Jacket and Sunday-night with Grace Potter, George Ezra and more – it’s time to announce the core crew of bands that will be hanging out with us at Wiggins Park and Susquehanna Bank Center from July 24th through the 26th.

Joining previously-announced headliners St. Vincent and My Morning Jacket on the line-up are several XPN member favorites who are XPN Fest alums, including Dawes, Lord Huron, Delta Rae, KopeckyField Report and JD McPherson. Melbourne, Australia singer-songwriter sensation Courtney Barnett, Brooklyn’s The Lone Bellow and Swedish sister duo First Aid Kit will make their highly anticipated festival debuts.

North Mississippi All Stars will be performing again, but this time they’re joined by Robert Randolph and John Medeski in their funk / blues / rock supergroup The Word.

And of course we can’t forget the homegrown acts, many of whom are beginning to take their music outside of the city limits. Electro-pop band Vita & The Woolf, R&B group Milton, Jersey indie rock four-piece Pine Barons and dream-pop outfit Cheerleader were tapped to represent Philadelphia after wowing the crowds at SXSW. Aaron Livingston’s exciting new project Son Little will also perform, as will pop singer Cole Redding.

There are also a few out-of-state (and out-of-country) up-and-comers, including Israel Nash (who we met at a Free at Noon earlier this year), mother-son duo Madisen Ward and the Mama BearFly Golden Eagle (who recorded a killer World Cafe session) and the hypnotic Bombino, who will perform desert rock straight from Niger.

The festival will also bring two special XPN projects to life. World Cafe‘s Latin Roots series brings musician Gina Chavez up from Texas, while Buckwheat Zydeco and Lost Bayou Ramblers throw in some Southwest Louisiana flair in conjunction with Zydeco Crossroads (which was kicked-off last time around with CJ Chenier’s knock-out set).

UPDATE: Hop Along, Calexico, Indigo Girls and Rayland Baxter have been added to the XPoNential Music Festival lineup; Hop Along and Calexico play Saturday, Indigo Girls and Rayland Baxter play Sunday.
