This is Alfredo Huang, a Taiwanese guitarist who I met years ago, during my first visit to Taiwan. He is a very active player who works as a soloist as well as an accompanist, mainly of the Korean soprano Ko Suk-Kyung, his wife and former fellow student at the Real Conservatorio de Madrid.
Besides as a performer, Alfredo is also very much appreciated as a professor. He regularly shows videos of his students on the internet like this, of a guitar quartet of which all members are playing my instruments.
