“Under the Radar Festival” director Mark Russell discusses the 2018 festival, along with Kelly Copper and Pavol Liska, from the Obie Award-winning Nature Theater of Oklahoma performance group. Copper and Liska also talk about their UTR show, Pursuit of Happiness. Created in collaboration with six dancers of the highly acclaimed Slovenian dance company EnKnapGroup, the piece charges through a rough-and-tumble, endlessly morphing myth of the Wild West. “Pursuit of Happiness” runs January 12-14  at NYU Skirball (566 LaGuardia Place).
