Last Friday, Sam Smith excited fans by inviting special guest Sienna Spiro to join their show during the “To Be Free: San Francisco” residency at the Castro Theatre. This performance was special as it celebrated the venue’s reopening after two years of renovations.
Along with Sam’s popular songs and previews of new music, the audience enjoyed a beautiful duet of SIENNA’s hit song, “Die On This Hill.” It was a nice moment since SIENNA had recently opened for Sam’s six-night “To Be Free: New York City” residency in late 2025, where they performed a memorable duet of Sam’s song “Lay Me Down.”
Sienna Spiro’s new single “The Visitor”
After her success of “Die On This Hill,” which recently reached No. 1 on Spotify’s Malaysia Top 50 Daily Chart, Sienna Spiro is set to release her new single, “The Visitor,” out 13 March 2026.

With her increasingly renowned mix of staggering vocals, emotional storytelling, and immense poise, it’s almost impossible to believe that SIENNA is just 20 years old. And yet, she’s found a global audience by not only releasing cinematic, soulful, and timeless yet subtly modern songs, but also — especially — by performing them live to jaw-dropping effect. A DIY-minded artist who first started penning songs when she was only 10, SIENNA’s earliest inspirations included Frank Ocean, Etta James, Frank Sinatra, and Amy Winehouse. She soon began integrating jazz elements into her music while gently leaning toward more contemporary sonic aesthetics, as heard on her stunning early 2025 debut EP SINK NOW, SWIM LATER.
She turned plenty of heads then, bringing breakout track “MAYBE” to The Late Show with Stephen Colbert, joining Teddy Swims on his summer U.S. tour, and stopping by COLORSxSTUDIOS to play her track “Dream Police,” but things accelerated quickly from there. Now, with a new project on the way, SIENNA SPIRO is continuing to evolve. She’s figuring out before our eyes where she stands when it comes to love, femininity, and adulthood, and is building an immersive world to match.
