Haftbefehl is a chain-dripping German rapper who has released a series of delirious LPs over the course of his long career. Till Lindemann, on the other hand, is best known as the fire-spewing growler at the heart of Rammstein, personally responsible for that band's Count von Count crunch.
Somehow, these two forces combined on Lindemann's latest solo cut "Mathematik," the video for which sees the two German vampires rapping in what appears to be some sort of subterranean post-apocalyptic prison system. (There are also multiple scenes where Lindemann is dressed up as a Japanese schoolgirl, which honestly should come with a trigger warning.) We have no idea what the song is about, but we're going to guess that it doesn't have a lot to do with algebra. Haftbefehl's verse is pretty impressive, though. We need to get him on a Kreator track next. Listen — and watch, if you dare — above.
