In 2021, Sienna started sharing covers and tiny original snippets online, building a loyal following thanks to her soulful, unpolished voice. Her breakthrough came in 2024 with her debut single, Need Me, followed by Maybe—which landed on the UK Singles Chart—and other heartfelt tracks like Taxi Driver and Back to Blonde.
