South African hardcore hip hop. Surreal, fetishistic, spiritualist, and totally profane. I've been following Die Antwoord since they made a splash early this year on Boing Boing. This video is too good and weird to pass up.
Bonus points: a scene in the video includes "Ninja" with a "prawn" (or alien) arm, which is a reference to the scifi thriller "District 9." I've just used this film, in which aliens end up in a refugee camp in the middle of Johannesburg, in a course.
