Guest List: Summer Cem

A protégé of German rap pioneers Eko Fresh, this son of Turkish immigrants is known for his hard-hitting lyrics. His notable guest spots span big club tunes like P.A. Sports' Bollywood-sampling "Kamagra", the future-trap synths of Farid Bang's "Russische Diät" and the jazzy New York hip-hop of Capkekz's "Taub, Stumm und Blind".
