A play based on the 2010 Upper Big Branch coal mining disaster that killed 29 miners will be performed in southern West Virginia next month. “Coal Country” recently ended an off-Broadway run in New York City. The play’s dialogue is taken directly from dozens of interviews with survivors and family members conducted by husband-and-wife team Jessica Blank and Erik Jensen. Theatre West Virginia will bring the entire production to Woodrow Wilson High School’s auditorium in Beckley on May 9 for a free performance.
