Cherry Filter (체리필터) is a Korean rock band that was started by Jijonbo and his long time friends in 1997. They were mostly underground until their second album "Made in Korea?" became an instant hit with its single "Nangman Goyangi" (낭만 고양이). Since then, Cherry Filter has become one of the most popular Korean bands around. In 2001, Youjeen (their vocalist), left for a while to have a solo career in Japan before the band had made it big.
