Natalie Imbruglia on perimenopause, career reinvention and her new album Algorithm

Natalie Imbruglia walks in circles when she writes. It's not a quirk—it's how melodies come to her, how she catches them before they slip away. Sit her in a chair, and nothing happens. Put her in a shoebox studio, and she panics about where she'll pace. During the making of her seventh album, Algorithm, she completed countless laps, though she's lost count. The record itself gleams with dancefloor energy, drawing inspiration from Talking Heads and Grace Jones, but beneath those shimmering surfaces lies something harder to look at: lyrics about the unraveling of her mind.

At 51, Imbruglia has spent the last five years navigating perimenopause, and she's put that experience directly into the album's centerpiece, a song called Who Dimmed The Lights. The condition, she explains, isn't simply about hormones fluctuating. It's neurological. The brain needs estrogen to function properly, and when those levels swing, spatial awareness goes first. She walked into doorways constantly. Brain fog settled in like weather. But the physical stumbles were minor compared to what happened in her mind. Perimenopause exacerbated an ADHD diagnosis she'd received in midlife. Anxiety spiked. Her anger became something she couldn't recognize in herself. People's faces would shift when she spoke—that look of confusion, of wondering what was happening to her. Her fuse had shortened. Processing information became difficult. She became sensitive to sound, interpreting normal conversation as shouting. Questions felt impossible to answer.

On tour, the anxiety became unbearable. Stage fright, which she'd managed for decades, went into overdrive. She became twitchy, weird, hypersensitive. One day, after a concert, she told her co-writers David Sneddon and Anu Pillai that she thought she'd have to quit performing altogether. She couldn't cope with how she was treating her team before shows. She was trying to force herself into compliance through sheer willpower, resisting the anxiety rather than accepting it. Sneddon and Pillai helped her reframe what was happening: nervousness before performing in front of thousands of people is natural. Resistance only amplified it. That conversation became a song, Upside Down. But Imbruglia remains frustrated that perimenopause remains so poorly understood. Many women, she says, are turned away by their GPs when they ask for HRT treatment. Her own mother never discussed it with her, though looking back, Imbruglia recognizes her mother had a severe experience of it—anxiety off the charts, raising four children. Now Imbruglia has compassion she didn't have before, having only one child herself.

Her path to this moment began in Sydney, where she was a performing child, squeezing lemon into her hair to lighten it, staging Whitney Houston concerts for neighbors. She appeared in Coca-Cola and Twisties commercials, sang carols in shopping centers at Christmas. By 15 or 16, when boys mattered more than performance, she rejected it all as uncool. She became, by her own account, basically unparentable—sneaking out, sleeping in someone's car on the beach, getting caught, her strict mother showing up at parties with her photograph. Socially, it was a disaster. But music remained her anchor. She dated a drummer, switched her allegiances from Whitney Houston to Tom Waits and Tori Amos. In 1992, at 15, she pressed herself against the barriers at an INXS concert, wearing white tight jeans, studying Michael Hutchence with what she describes as determination in her eyes, thinking: How can I be up there too?

She got her answer in 1997. After quitting her role as Beth Brennan on the Australian soap Neighbours, she moved to London, signed with RCA Records, and released Torn as her debut single. It was a cover—a fact that journalists never stopped reminding her of, even though she co-wrote every other track on her debut album, Left of the Middle, which sold seven million copies worldwide. The song was a gift, she says now, but the constant focus on the fact that she didn't write it fed her insecurities. She essentially sabotaged her own career in response. Her second album's lead single, That Day, was a free-verse stream-of-consciousness with no chorus—a deliberate rebellion. She was young, just learning songwriting, and hadn't asked for any of this. She wanted her life back.

In the chaos, she auditioned for Satine in Baz Luhrmann's Moulin Rouge. The audition, she recalls with a grimace, was essentially an instruction to simulate an orgasm, since that's what happens in the film. It wasn't a casting couch situation—Luhrmann isn't that kind of director—but she left feeling icky, wanting her mother. Back in music, she returned to more commercial territory with Wrong Impression and Shiver, but sales declined. Her fourth album was shelved. She joined the Australian X Factor, appeared in a stage production, made a covers album called Male in 2015, and returned to personal songwriting with Firebird in 2021. The break from music, she says, gave her something she'd lost: appreciation for what she could actually do. She might not be the best songwriter, but there's only one her. When she goes inside herself and feels the emotion of what she's writing, that's what her fans respond to. That's enough.

Algorithm carries a lot of that hard-won self-knowledge. Beyond the perimenopause material, the title track addresses her flirtation with internet conspiracy theories—she won't specify which ones, calling it irresponsible to name them, but she stresses the danger is constant. There's a compulsion to click, to scroll, to feed anxiety through a phone in bed. You have to change the settings, she says. You have to stop allowing your stress relief to come from a screen. The album ends, though, on something lighter. Beautiful Love, co-written with Snow Patrol's Gary Lightbody, is a soaring hymn to embracing your flaws and accepting life's swings. She's made a joke for years that she'll never be Buddhist because she loves the pendulum—extreme joy, extreme pain, the full experience of being alive. Algorithm, in its way, is that pendulum captured in sound.
