Nerd Africa? That was Riccardo Tisci's label for his Givenchy collection, though it wasn't the first thing that came to mind when his distinctly un-nerdy warriors had filed off the catwalk. Techno-tribalism maybe; Tisci's prints were based on the technology of sound dissected and reconfigured as tribal patterns. Boom boxes and reel-to-reels and home studios broken down into their component parts, rearranged in a perfectly symmetrical pattern, detailed in bright primary colors—that was Tisci's news for today.
