Generation Bass posted this amazing video a while back:

Soo i went & followed the links & found Die Antwoord's website where you can download loads of their tunes for free! All equally insane! My favourite so far is Doosdronk with it's electro-oompah beat, vocals slipping from Afrikaans (I think! apologies if I'm wrong) into English and back, then rocking out a bit for the chorus... and at about 2.30 what sounds like a crazy liverpudlian... fook yauu!

Grab it here... Die Antwoord - Doosdronk
