Hyeyung was appointed a violinist of the Del Sol Quartet in April 2023.

​

Fascinated by the feedback loop between social change, technology, and artistic innovation, the 

San Francisco-based Del Sol Quartet is a leading force in 21st-century chamber music. They believe that live music can, and should, happen anywhere – whether introducing Ben Johnston’s microtonal Americana at the Library of Congress or in a canyon cave, taking Aeryn Santillan’s gun-violence memorial to the streets of the Mission District, or collaborating with Huang Ruo and the anonymous Chinese poets who carved their words into the walls of the Angel Island Immigration Station. Since 1992, Del Sol has commissioned and premiered thousands of new works.
