Without her friend and muse, Sophie, Charli XCX is still the face of stretched balloon aesthetics and jacked up emotional and spatial perception. “Crash” is a hammering Eighties rewiring of vocal fry, as is a good third of the album. She and producer AG Cook can get Caroline Polachek on the phone but they mostly skip the guests and run through their Eighties playbook, including sneaky rewrites of Eurhythmics and Lisa Lisa and Madonna. There’s a certain wired state that Charli really owns at this point and we would all be poorer without it.
