Auckland’s Chaos in the CBD have an EP out on Monday, and the first single beautifully and obviously samples Ms. Diana Ross. On Jim-E Stack’s remix, that sample is rendered barely recognizable. It’s a trick Stack has been known to relish in, curbing a sweet lady’s vocal until it’s purely prehistoric and percussive. At around the 3:11 mark, that effect feels its most primal, with Ross’ high notes stuttered so wildly it hits every corner of your brain like a tiny little reflex hammer making all your joints jump.
