Allie X is a shape-shifter, with a laser-precise soprano that evokes, by turns, Lana del Rey’s Technicolor ennui, Lauren Mayberry’s clarion sighs and Alessia Cara’s introvert smoulder. The singer, songwriter and producer honed her craft as a musical-theatre kid in early-aughts Toronto, making an indie-rock detour before going west. In Los Angeles, she reinvented herself as a stylised enigma known for fusing cryptic lyrics and exhilarating hooks, winning fans (including Katy Perry) with 2014’s “Catch”, a moody, synth-driven opus. A pop savant, she uses those skills to execute conceptual visions—like 2018’s Super Sunset, essentially an L.A.–themed rock opera.
