Biography
Leessang (리쌍) is a Korean hip hop duo, comprised of Kang Hee-gun ("Gary") and Gill Seong-joon ("Gill"). Formed in 2002, Leessang is known for its collaborations with Drunken Tiger, T, Big Mama King, Park Hwayobi, and many others.
Both members were once a part of a large Hip-Hop group called Honey Family. They fair share of popularity with their debut single 'Rush' which contained a sample from the American group the Stylistics. The members of Leessang are also part of the Hip-Hop coalition known as The Movement, which was started by Drunken Tiger.
Leessang is a 2-member rap band made up of Gary and Gill, ex-member of Honey Family. Avoiding the strong and aggressive style, Leessang pursues a relaxing and flexible rap in which the rhythms are alive. Humor and wit, and the utilization of a retrospective sound are the strong point of the rap duo. The duo first was created in 2002. The members of Leessang first put their feet in the show biz by participating as guest rappers for a band called Exteen in 1997. In 1999, the members of the duo joined a hip-hop crew called Honey Family. Gary and Gill participated in the production of two albums with Honey Family, “A Man’s Story” and “Another Level.” The two rappers showed off a unique style of melodic rap with the band. When there was a lull in Honey Family’s performing activities, Gary and Gill separated from the band to start performing as a duo. Under the name of Leessang, the two rappers released their first album in 2002. Accompanied by some top figures of the local pop music scene including Park Hwayobi, Jung-in, Park Seon-joo and Bubble Sisters, Leessang displayed a fantastic harmony of rapping in their first album. Almost all the words of Leessang’s rap were written in Korean showing the essences of a so-called ‘indigenous hip-hop.’ Acknowledged for their talents in hip-hop music, Leessang was invited by Seo Taiji to the '2002 ETPFEST.'
The duo has released 4 albums to date: two self-titled records in 2002 and 2003, "Library of Soul" in 2005, and Black Sun in 2007.
