This is a live recording from a piece I did in May 2012 in Hsinchu, Taiwan, at the invitation of the Taiwan Computer Music Association. It was an excellent program of works by various Taiwanese composers of music with computers (Jeff Huang. Chao Ming Tung, TZENG Shingkwei and orthers). I was invited to do a piece together with composer Tzeng Shing-kwei and, before that, to do some of my own work. So I first did this piece for extended vocal techniques, and also using a Sakha (Siberian) Jew's harp (or khomus), thereby losely incorporating elements from typical computer generated sounds. Part II is a longer piece of overtone singing with drones from a shruti box. Part II is the duetto for live electronics and voices with composer Tzeng.
