“Yeah bitch I’m here to take that crown,” yelps Charli XCX atop the pulverising, MIA-indebted neo-rave of “Trophy”. And if you’re looking for a sign of the former Charlotte Aitchison’s alt-pop reign, you could do a lot worse than this experiment in tyre-screeching electro provocation. Wholly produced by SOPHIE—of disruptive London label PC Music—and predominantly recorded in just a few days, Vroom Vroom EP fizzes with in-your-face inventiveness and unstoppable youthful brio.
