She shares her passion across three flagship shows: Future Artists, The Chillest Show, and The Power Down Playlist. Each week, she champions artists from rising stars to household names, including interviews with Chappell Roan, RAYE, Hayley Williams, Olivia Dean, Gracie Abrams, CMAT, Role Model, Wolf Alice, and many more.
Since 2024, Sian has hosted a weekly show on Selector Radio, connecting a global audience to the UK music scene across more than 30 countries. The show has also taken her to host live gigs around the world - from Osaka to Austin, Texas.
Her love of documentary-making led to presenting the hit BBC Three series Paranormal, watched by millions and nominated for multiple awards. Across all three series - available on iPlayer - Sian brings curiosity and empathy to every story. She is currently filming a solo BBC documentary on painter Gwen John, featuring an interview with fashion icon Jonathan Anderson, due for release in 2026.
In 2025, Sian was selected to present the new Welsh-language version of The Voice for S4C, joining one of the world’s most successful entertainment formats. Filming for Series 2 begins in winter 2025. Other TV credits include live BBC coverage from Reading Festival, BBC One Wales’ cultural programme Green Space Dark Skies, Merched Yn Gwneud Miwsig for S4C (celebrating women in music), and Celebrity Gogglebocs.
Named Music Week’s Rising Star in August 2021, Sian’s deep expertise in music has seen her serve on several prestigious judging panels, including the Mercury Prize (2023–2025), the BRITs, the AIM Awards, the Youth Music Awards, the British Podcast Awards, and the Welsh Music Prize.
Sian also has extensive experience hosting live events, where her presenting style is consistently described as warm, accessible, and engaging. Whether presenting at Glastonbury, guiding audiences through BBC Proms, or hosting the Welsh Music Prize, she brings a relaxed confidence and genuine enthusiasm that makes every moment feel personal. Other career highlights include Radio 1’s Big Weekend, the British Society of Magazine Editors (BSME) Awards, and red carpet coverage at the BIFA Awards. She also curates her own gig night, TONNA’, spotlighting some of her favourite emerging artists - with more events planned for 2026.
Sian is a sought-after voiceover artist, with clients including Google, the Women’s Euros, BBC Archives, 4Music, HMRC, and the Six Nations Championship. She narrates the popular BBC Wales series SOS Extreme Rescues, and her voice can also be heard on the BBC podcast Story of Miwsig alongside DJ Huw Stephens, and across various BBC Sounds playlists.
She recently partnered with Barbour International as the face of their Badge of an Original campaign - a celebration of trailblazers who forge their own path. Sian has also been profiled by Notion Magazine as a rising star in British music and broadcasting.
Whether on air, on stage, or behind the mic, Sian brings people closer to music - with curiosity, care, and a voice that feels like home.
