Hiya!
Lately... Die Antwoord. Normally I'm not a "rap guy", but I like these two. Interesting sounding and a nice blending of "rap and techno/dance". And they both (Ninja in particular, but also Yo Landi) have a REALLY cool imagination in regards to film making and song-story-telling-music-video (go search for Die Antwoord Alien song; GREAT music video!)
