about
Pierre Flasse is a composer, sound designer and performer creating original music and sound for stage, screen and live performance.
With a background spanning classical music, jazz performance and years of electronic experimentation, his work feeds into a practical, collaborative approach to sound—one that blends styles naturally and helps shape the tone of each project. He especially loves diving into new writing, process-led devising and projects that speak to social and political issues.
Pierre leads his own spiritual jazz group and works as Composer’s Assistant to filmmaker and composer Sally Potter OBE. He has received mentoring Pete Malkin and Ella Wahlström with support from the Association for Sound Design and Production and he was also an inaugural Elemental Artist with the Watermill Theatre in 2024.
Across everything he does, Pierre brings a warm, open approach and a distinctive musical voice shaped by curiosity, exploration and play.
"Pierre Flasse’s music is perfectly matched to its own storytelling journey. The score he has composed for this piece feels like a narrative in itself, helping to shape and contain the action. Every sound feels purposeful. "
- All That Dazzles on Foal
"With minimal set but expertly deployed sound Pierre Flasse works wonders to create an atmosphere that veers from humorous banter to simmering tension and ultimately explosive energy."
- The Peg on Miraculous
"The design choices amplify this energy: Pierre Flasse’s sound design is loud and unforgiving. Together, with Nathanael Campbell's exceptional direction, they create a world that feels both celebratory and claustrophobic, a perfect reflection of the play’s themes."
- All That Dazzles on Limp Wrist and the Iron Fist
"Permission’s technical design is also revelatory ... Pierre Flasse [is] at the top of [his] game, elevating the relatively small stage space in Tara Theatre. It is hard to communicate in words how effective the design was, one almost forgot that it was there because of how immersive it made the world."
- A Youngish Perspective on Permission
"This bleeds into a distant chorus of echoing, boisterous male laughter and footsteps, instantly creating a genuinely terrifying atmosphere."
