Blending hypnotic synth-pop, hedonistic club energy, and brutally honest songwriting, Estrus explores themes of womanhood, identity, desire, self-destruction, family tension, and emotional contradiction. Tove Lo has described the album title as representing “an animal in heat” — something instinctive, impulsive, and impossible to fully control — reflecting a record where mind and body constantly pull in different directions. Rather than offering neat conclusions, the album embraces uncertainty and emotional overload, driven by what she calls “a lot of feelings, no solutions.”

Created alongside longtime collaborator Ludvig Söderberg — whom Tove Lo calls “the second half” of herself creatively — as well as producers Elvira Anderfjärd and Luka Kloser, the album marks a continuation of the fearless alternative-pop sound that has defined her career while pushing deeper into vulnerability and instinct-driven songwriting. Inspired by boundary-pushing Scandinavian pop artists like Robyn, Estrus balances explosive hooks with emotional rawness, embracing messiness instead of resisting it.
