은지원 (English: Eun Ji Won, Eun JiWon Aliases: G1) born June 8, 1978, is a Korean musician and leader of the 90s boy group Sechskies. After the group initially disbanded in 2000, he started his solo career in 2001 under the name G1. Out of all of the members of Sechskies, he was heavily criticized after the disbandment. This arose from the fact that he changed genres from pop, to hip-hop and rap. In mid-2006, he joined The Movement, a group of rappers from all over Korea.
