According to a promosheet, enclosed in‚ 'Das Hohelied Salomos‘, Djong Yun received education in singing from „Frau Winterfels“ who was also the teacher of the famous baritone Dietrich Fischer-Dieskau. Probably Margarethe von Winterfeldt is meant here, who worked in Berlin until her death in 1978.
She's the daughter of the modern classical composer Isang Yung who's Professor at the Berlin Music School and wrote the Opera for the Munich Olympics.
Florian Fricke, Conny Veit and Djong Yun performed as a band in Lieberkosen and Munich.
Florian Fricke met Djong Yun while living in Munich in Halachein. Musicians from other towns and cities that came to town came to Munich came by his house, and were jamming. One day Djong Yun came there. Florian was playing with Andy Fix, the guitar player, and he was talking about this incredible girl from Berlin, this singer from Berlin, and he said that I had to meet her. Florian was working with Esther Ofarim in those days, but it didn't work out because she refused to sing Christian lyrics, being Jewish I guess, so she didn't want to interpret this kind of song. In those days there was not this competitive feeling among musicians, and the contacts were loose and open. People were just visiting each other for the sake of music, and not to discuss their recording contracts. In a certain way we were all hippies in those days.
Nowadays Djong Yun lives in South Korea, working for the Isang Yun Peace Foundation as representative director. It is the first commemoration organization named after her father, the composer, Isang Yun. There is International Isang Yun Society in Germany, Isang Yun Music Institute in North Korea. It was established in March 2005 and hosted an annual event on the 10th anniversary of my father's death in same year.
