Dierks Bentley and Lee Brice have been added to the lineup for "C’Ya On The Flip Side," an upcoming concert in Nashville benefitting the Troy Gentry Foundation. MusicRow reports that Colt Ford, Tracy Lawrence, Ray Scott, and Darryl Worley are also new additions to the event, which will take place January 9 at the Grand Ole Opry. Previously announced performers include Blake Shelton, Jon Pardi, Rascal Flatts, Jimmie Allen, Halfway to Hazard, Chris Janson, Dustin Lynch, Justin Moore, Craig Morgan--and of course, Montgomery Gentry's other half, Eddie Montgomery. The Troy Gentry Foundation was formed in the wake of the 50-year-old country singer's death in a helicopter crash last year. Proceeds from the concert will go toward the Journey Home Project, as well as music education in Kentucky schools.
