尹伊桑
After 1979 Yun returned several times to North Korea to introduce new Western composition techniques as well as his own music. In 1982, the first Isang Yun Festival took place in Pyongyang. In 1984, the Isang Yun Music Institute opened in Pyongyang, North Korea. An ensemble had been founded there under his name. Yun promoted the idea of a joint concert featuring musicians from both Koreas in Panmunjom, which failed in 1988, but South Korean artists could be invited to Pyongyang in 1990.
