Chlyklass is a rap-collaboration from Bern, Switzerland, that contains "PVP" (Greis, Phantwo, Poul Prügu, Krust), "Wurzel 5" (Diens, Serej, Tiersch) and "Baze" (solo artist). Because of their friendship and of course their collectively love to Hip-Hop, they established "Chlyklass" in 1999 to bring the sound in their own native language to the swiss crowd. official website wikipedia article (german) .
