Monday night -- the late-night television crowd. For those who'd never been exposed to the South African rappers before, their appearance on David Letterman may have been slightly terrifying, a sentiment shared by some South Africans who take issue with being represented by the trio. For the rest of us, this was a tamer version of the shock rappers: Yo-Landi looked as bug-eyed as always in a pair of black contacts and long white t-shirt (Alexander Wang?), DJ Hi-Tek wore a deformed face mask, and Ninja danced frantically in a orange jumpsuit to their clubby single, "I Fink U Freeky," off their just-released album Ten$ion.
