Rip Slyme (often stylized as RIP SLYME) is a Japanese hip hop group. It is composed of four MCs; Ryo-Z, Ilmari, Pes & Su, and a DJ, Fumiya. Their sound derives its influences from old school hip hop and other Hip Hop such as The Pharcyde, De La Soul, Public Enemy, Jurassic 5, the Beastie Boys, DJ Premier, Leaders of the New School.
The group was formed in 1994 by Ryo-Z and Ilmari, who were later joined by Pes (he attended the same school as Ilmari). The Rip in Rip Slyme stands for their initials. Slyme was a popular children's toy at that time. Their name is also a pun on the phrase "lips' rhyme". Winning an amateur rapping contest "Young MCs In Town", they started their musical career with their first album Lips Rhyme in 1995. Later they added DJ Fumiya (who had studied under East End X Yuri's DJ Yoggy) and Su (previously a backup dancer for East End X Yuri).
