Today joined a nice program of computer music from my friend, composer and professor Tzeng Shingkwei. I heard some wonderful versions of Hakka singing with piano and/or electronics, electro-acoustic music by a Tarogo composer/improvisor and some excellent vintage-sounding electronic music studio work – almost like early Stockhausen works. Then I gave my vocal response to this digital input (also using a Sakha Jew’s harp) and sang some overtones with my sruti box. Finally, professor Tzeng and I did a new piece of him together, with live sampling/effects of our voices.
