Premise: 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 and Leaders of the New School.
Hypothesis: RIP SLYME are all fluent in Japanese.
