On April 1, big names in K-Pop including Red Velvet, Baek Ji Young, Jo Yong Pil, and more performed at the North Korea concert in Pyongyang. The historical event successfully drew to a close, however, many still questioned why Psy and BTS - the artists who played major roles in spreading K-Pop to the world - were left out of the lineup. 

A government official answered the question in an interview with the press on April 1. Regarding Psy, the official stated, "They [North Korea] had a certain image in mind and thought he would stand out too much from that image." As for BTS' absence, the official simply commented, "Because of their schedule."
