The weirdos, God creates them and they gather: last week those behind new festival the London Electronic Dance Festival, which will take place this weekend (Friday and Saturday in Victoria Park), dedicated a post to the ten performances that are not to be missed. On the list, among Goldfrapp, Friendly Fires and Professor Green, were the genius Richard D. James , and Die Antwoord, South-African paladins of this hybrid of hip-hop and rave music they call zef-rap. What the L.E.D. people forgot to tell us is that they’re going to collaborate. Two days ago, Ninja tweeted that he and his partner Yo-Landi will be emceeing with the “Grand Master himself”, aka Aphex Twin, at L.E.D. Pitchfork asked Interscope, Die Antwoord’s American label, about it, and it seems to be true. It will certainly be memorable.
