Kim Petras became the toast of the pop world with her 2017 breakthrough single “I Don’t Want It At All,” a neon-hued demand for life’s finer things that showcases her brash voice and take-no-prisoners attitude. Since then, the German-born, Los Angeles-based upstart has become one of the brightest stars dwelling on pop’s arch, synth-heavy edge, collaborating with fellow forward-thinkers like Charli XCX and SOPHIE on hooky, futuristic bangers and releasing a Halloween EP, Turn off the Light, Vol. 1, that put the spotlight on her darker side.
