The Duo Spiritual is a long-standing collegiate team since 2003 with innovative marimba soloist Humphrey Leung and versatile pianist Tin-Chi Siu both graduated from the Chinese University of Hong Kong. After that, Humphrey  and Chi continued their musical study abroad in different countries; however, they still managed to keep performing as duo with new ideas at the same time. The group endeavors to explore the musical possibilities across marimba and piano and brings positive vibe to the world. The combination of the two instruments allows the group to perform a wide range of musical styles including classical, contemporary, as well as pop and jazz. The group is also deeply involved in crossing over with other performing art media.
