Sienna Spiro

On 15 May 2026 at O2 Academy Glasgow, Sienna Spiro brings her voice-led blend of soul, pop and R&B to the stage. The UK singer-songwriter built her name with intimate writing and agile melodies, drawing on the vocal tradition of jazz greats like Etta James and Frank Sinatra while keeping a foot in the early‑2000s hip‑hop she grew up with. After posting covers and early drafts on TikTok from 2021, she stepped out with Need Me in May 2024, then Maybe in August, a track that nudged the charts and carried her to All Points East. Taxi Driver and Back to Blonde followed that autumn, and Dazed flagged her as one to watch. Butterfly Effect arrived in January 2025 ahead of her first EP, Sink Now, Swim Later, released on 21 February 2025, a set of sparse, soulful ballads balanced with a pop sensibility. By autumn 2025, Die on This Hill reached the UK top 10 and anchored a growing catalogue. Live, expect a focused set that threads these singles with newer cuts, spotlighting harmonies, clear storytelling and uncluttered production.
