Lee began his musical career as a bassist in a band supporting pop singer
Kim Wan-sun. He received an offer for a solo debut from Kim Kwangsoo, now head of
MBK Entertainment, in 1990 and released an album incorporating synthpop elements entitled
Vol.1 to commercial success.
Vol.1 was followed with
Vol.2 Part 1 in 1992 and
Vol.2 Part 2 in 1993.
Vol.2 was the more avant-garde and experimental of the two albums but still found commercial success. The title song, "가려진 시간 사이로 (Between The Hidden Time / Between the Veiled Times)" was especially popular. Lee's third album release,
Renacimiento in 1996, consists of remakes of songs from his previous albums sung by French, Italian and American vocals with redone lyrics.
Renacimiento was one of the first mainstream albums in Korea incorporating the world music genre and was also popular. Yoon Sang also released a techno album entitled
Golden Hits as part of the music collaborative project "NoDance" with rock artist
Shin Hae-chul. After releasing
移徙 이사 (
Migration) in 2002 Yoon Sang worked on composing and lyric-writing for SM Entertainment, penning songs for
BoA and
TVXQ, among other artists. In 2003 he released
There Is A Man..., his fifth album, which incorporated rap, Latin, and
electronic dance music. A track from that album entitled "길은 계속된다 (The road continues)" also incorporated
glitch music. In 2008, Lee released a
tribute album called
YOONSANG SONGBOOK : Play With Him! with covers by many Korean groups, including electronic duo
Peppertones and rock band
My Aunt Mary. In 2009 Lee released an eponymous glitch-focused album as part of project group called "" with fellow Korean musicians Kayip and Superdrive. The group was formed while Lee spent two semesters at the
NYU School of Music Technology. Both Kayip () and Superdrive () were experienced with electronic and
IDM-focused music and Lee wanted to expand awareness of these types of music domestically. They finished producing the record by sending files over email and MySpace and held a showcase for the album at
Hongik University. In 2015 Yoon Sang participated in the
Infinite Challenge Music Festival and was partnered with cast member
Jeong Jun-ha. In 2019 he was a judge in the
