Vulgarity can make for interesting (if not exactly radio-friendly) music, as long as you know how to pull off “trashy, yet flashy.” According to the Cape Town-native hip-hop trio Die Antwoord (which means “The Answer” in Afrikaans), the band’s outrageous approach is remnant of Zef, a South-African style that emanates many things glitzy and glamorous yet simultaneously hard and raunchy. Die Antwoord specializes in odd, catchy hooks and is far from afraid to douse its music videos with racy scenes and creepy visuals. Band members Ninja, Yo-Landi Vi$$er, and DJ Hi-Tek might seem a bit scary with their in-your-face, outlandish appearances and antics—but are musically skilled and stay true to their own interpretations of what it means to live and speak freely. Die Antwoord performs at 9 p.m. at The Trocadero; tickets to the 18+ show are $22 – $24. —Lisa Henderson
