For both a trick and a treat try the South African rap-rave group Die Antwoord. Formed in 2008 and fronted by rappers Ninja and Yo-Landi Vi$$er and backed by DJ Hi-Tek. Their lyrics are performed in Afrikaans, Xhosa and English. Their image involves counterculture movement called Zef, the nasty, freaky, gleefully trashy underbelly of post-apartheid white South African culture and the influence of photographer Roger Ballen whose black and white images has documented the small villages of South Africa. Totally Freeky.
