Greis is an MC from Switzerland and a member of the Bern-based rap-crew "Chlyklass" (small grade of school) After his solo debut "EIS" (Swiss-german for "One") in 2003 he went on to release albums with his crews PVP and Chlyklass, as well as a collaboration album with Curse, Taz, and Claud, and countless guest appearances. In Winter 2007 he released his second album simply called "2". Special feature: the whole album has been recorded twice on two CDs. One in Swiss-german, the other one in French. So it is possible for almost 90% of Swiss people to understand his lyrics! .
