1997–2000: Sechs Kies Lee and
Kim Jae-duck formed a dance crew called "Quicksilver’" in their hometown of
Busan, and was selected as a trainee in Lee Juno's company. Lee Juno was famous as Seo Taiji and Boys' member. At that time Lee Ho-yeon,
Daesung Entertainment's CEO, asked him to recommend a idol group member. That is how he became a Sechs Kies' member. In 2016,
Kang Sung-hoon said that he had watched the audition tape and chosen Lee as a member for his superior dancing skill and good looks. Lee debuted as a member of
Sechs Kies, signed under Daesung Entertainment, in 1997. Along with Kim Jae-duck, he created the choreography for most of Sechs Kies' music videos. Sechs Kies achieved great success and became an icon of the 1990s Korean idol groups. However, Sechs Kies suddenly disbanded in 2000 after finishing their fourth album's promotion.
2000–2016: Solo career and other endeavors After Sechs Kies' disbandment, Lee was the third member from the group to begin a solo career. He released his first album, entitled
S.Wing with a hit song "Double J" in 2001. He released the following album,
002 J2 with a title song "Go Back" in 2003. However, it failed to see a great success compared to when he was performing as Sechs Kies. After three years of hiatus, he subsequently released his third album, entitled ''It's New'' with the hit song "Charge" in 2005. Lee began his
mandatory military service in 2006. After being released from the military, Lee withdrew from the entertainment industry and went to study in Japan. In 2011, Lee participated in
Big Bang's
Special Edition album, drawing illustrations for the five members. In 2013, Lee co-operated with his brother-in-law to open a new restaurant, School Food, in a YG Entertainment-owned building. In 2015 and 2016, he participated in group exhibitions, 상상연대 2 (Imagination Alliance 2) and 상상연대 3 (Imagination Alliance 3), in GALERIE GAIA under his pseudonym 한조 (Hanzo).
2016: Sechs Kies reunion In 2016, Lee and his former Sechs Kies bandmates, except
Ko Ji-yong, reunited on
Infinite Challenge. All members, except Ko, signed a contract with
YG Entertainment as a band, while Lee and Kang Sung-hoon also signed as solo artists. On August 19, Lee joined SBS's variety show
Flower Crew with
Eun Ji-won, however, withdrew from the show to focus on group promotions. == Personal life ==
