SA producer Jumping Back Slash enlists Spoek Mathambo to spit over his khawulezayo, lightning-speed remix of the The Frown's "Metallic Kiss." Spoek jumps in around the 1:40 mark delivering an equally rapid-fire, Xhosa-English verse and a howling outro. Listen/download "Metallic Kiss (Khawulezayo VIP ft. Spoek Mathambo)" below and check out Jumping Back Slash's excellent Uhambo Mixtape, which we premiered last month.
