Sienna Spiro

Sienna Spiro has a voice that lingers long after you hear it. At just 19, her soulful tone has already caught the attention of Snoh Aalegra, Finneas, and Mark Ronson.

Spiro first went viral on TikTok at 16 with a cover of Finneas’ Break My Heart Again, gaining over 23 million likes. Two years later, she released her debut single, Need Me, now at 3.5 million streams, leading up to her debut EP, Sink Now, Swim Later.

Raised in northwest London, Spiro was immersed in blues, soul, and jazz, crediting legends like Sarah Vaughan, Nina Simone, and Otis Redding for shaping her voice. She wrote her first song at 10 while struggling with bullying, using music as an escape. Open-mic nights in Chiswick built her confidence, though formal lessons frustrated her.

At 16, her career changed overnight when she uploaded a TikTok duet on her way to Reading Festival. Within weeks, she had a manager. After briefly attending music college, The-Dream (Beyoncé, Rihanna) reached out, leading her to Atlanta for real-life experience.

Her EP, crafted between ages 16 and 18, is shaped by producers like Yakob (SZA), Emile Haynie (Lana Del Rey), and Omer Fedi (Lil Nas X). With her synesthesia guiding the sound, the project divides into “sink” and “swim” songs, exploring struggle and triumph.

Since her debut, Spiro has 2 million monthly listeners and a sold-out headline show at London’s Hoxton Hall. With festival slots and Australian shows in 2025, she’s fully committed: “I would rather die than not be doing music.”

From viral moments to industry co-signs, Sienna Spiro is just getting started.
