Jess has been singing jazz for two decades.  From Jess's 1st jazz album, listen to "Dao" 

It's interesting that my jazz career developed in China. Little did I know that I would grace so many stages. And now I am known as China's best jazz vocalist, which, granted, there are not many jazz vocalists in China, but honestly, I feel that because I have had so many opportunities to perform jazz on stages, I am a well-weathered, professional jazz vocalists. Anyone who plays jazz knows that this statement isn't one utters as a mediocre or young jazz player. Good jazz is something that happens over time, with a great deal of listening, practicing and performing.

I've been really privileged in a sense to work with some really amazing jazz musicians over years, local and internationals. I've recorded one jazz album so far, entitled "DAO." There are 4 originals and 5 standards.
