Patty Griffin and John Hiatt, two of Americana music's most-awarded singers, will join forces to headline next month's Cross-County Lines Festival. The event, now in its second year, will be held on May 31, 2014 at the Park at Harlinsdale Farm in Franklin, Tenn.

This year's festival, which will also include performances by Ashley Monroe, Brandy Clark, Parker Millsap, Joe Pug and Luther Dickinson, is intended to raise awareness and support for the Americana Music Association's mission, which is to advocate and promote American roots music all over the world.

"The intent of this is not to create a Bonnaroo or CMA,"  Americana Music Association Executive Director Jed Hilly explains. "The intent is to create a cool vibe of a festival, celebrating the music and crossing county lines. And not just Nashville and Williamson [County]. We believe that this region from Nashville to Memphis, to New Orleans, by way of Muscle Shoals, is the cradle to great American roots music. We want to highlight that, and we want to take pride in the music we have created."

Doors for the Cross-County Lines Festival will open at 3:30 PM. Tickets are $35 per person. A Premier Patron VIP option also will be available for $150. Tickets are currently available for purchase here.
