He made his Western debut in Carnegie Recital Hall in 1979 and soon began performing and pre-recording in non-traditional settings, collaborating with Henry Kaiser, Laurie Anderson, Ryuichi Sakamoto, Jason Kao Hwang, and the Far East Side Band.
His trio with Henry Kaiser and Charles K. Noyes, called Invite the Spirit, was formed in the summer of 1983 and was probably the first free improvisation ensemble to integrate a Korean traditional musician.
The Far East Side Band is a multicultural music group with members from Chinese, Korean, Japanese, and African American backgrounds.
He was also featured in Derek Bailey's Improvisation television series on the UK's Channel 4, as well as films by Laurie Anderson and Nam June Paik.
For many years, Park has earned his living primarily from operating two flower shops in New York City.
