Emmylou Harris, Ted Leo, Gary Clark Jr. at the Xponential Fest

The WXPN-FM Xponential Music Festival kicks off today and carries on through Sunday at Wiggins Park along the waterfront in Camden. Tonight's headliner is the hard-to-get-excited-about Citizen Cope, but there are some choice selections on the undercard. Among today's top attractions is Gary Clark Jr., the new school Texas bluesman who wears "the future of the blues" nametag around his neck quite comfortably. The Smithereens and Joseph Arthur are also on tap today. My recommended choices over the weekend would include Jeff Bradshaw and Brass Heaven, Ted Leo and the Pharmacists, and Sun Airway on Saturday, and Kuf Knotz, Hayes Carll, Shemekia Copeland and Emmylou Harris (that's her) on Sunday. Clark tears it up at Eric Clapton's Crossroads Festival, below. The full schedule is here.
