Die Antwoord hit Letterman show

Check out South African rap-rave trio Die Antwoord do their freaky thing on Letterman.

Hard to know what the music booker at Late Night With David Letterman was thinking, letting the "unique" satirical art-terrorists on the show, but they recently hit the studio to perform their new single 'I Fink U Freeky'.

And freaky it was, although Dave got into the swing of it, suggesting that the act should've been on the Super Bowl Half-Time show after the crowd gave a nervous/relieved chuckle when the song concluded.

Die Antwoord's second album Ten$ion has just been released.

Check out Yo-Landi's black eyeballs and Ninja's sharp red tracksuit (which he sadly didn't tear off to reveal a fake phallus or his prison tattoos) below.
