Family Background
Spiro is the daughter of Glenn Spiro, a well-known fine jeweler, and Arabella Spiro, who works with Tikva UK, a charity supporting at-risk Jewish children. She grew up with three siblings in a household that exposed her early to music and film — her father introduced her to Frank Sinatra, Nina Simone, and classic Italian cinema, influences that show up clearly in her sound today.
Early Life and Education
Spiro began writing songs at age 10, starting with a track called “Lady in the Mirror,” and gave her first live performance at a pub near Heathrow not long after. She attended Francis Holland School before continuing at East London Arts & Music, ultimately leaving school at 16 to pursue music full-time.
Career: From TikTok to the Charts
Spiro started posting singing videos on TikTok in 2021 and built a large following through covers and original material. She began officially releasing music in 2024, with the single “Maybe” marking her first entry on the UK Singles Chart. Her debut EP, Sink Now, Swim Later, followed in February 2025.
Her real breakthrough came with “Die on This Hill” in late 2025, which reached the UK top 10 and led to a global publishing deal with Sony Music Publishing. Momentum carried into 2026: a BRIT Awards Critics’ Choice nomination, a performance on The Tonight Show Starring Jimmy Fallon, a surprise duet with Sam Smith, and her debut studio album, Visitor, released in July 2026.
Musical Style
Spiro’s sound blends jazz, soul, and contemporary pop, built around piano-driven arrangements and expressive, one-take vocal recordings. Critics have compared her voice to Adele and Amy Winehouse, and her own influences — Etta James, Nina Simone, Frank Sinatra — come through clearly in the vintage, emotionally direct feel of her songs.
What’s Next
With her debut album out and a widely-touring schedule underway, Spiro’s 2026 has moved her from viral TikTok artist to a genuine international touring act.
