Ben Walter is Head of Partnerships at Polygon Portal, London’s dedicated 360° spatial-audio listening room in Soho, powered by a state-of-the-art L-Acoustics 17.1.10 system. He leads Polygon’s relationships with artists, labels, brands, and cultural organisations, with recent work including Prince, Pink Floyd, De La Soul, UNKLE and the London Symphony Orchestra.

Polygon began in the festival world, creating immersive arenas and experiences at Wonderfruit, Bonnaroo and MDLBEAST, before bringing that experience into the intimate Portal. Polygon Live LDN was recently shortlisted for Best Live Production at the UK Festival Awards.

Following the success of 2026, Portal returns for Season 3 in March 2027, with a programme spanning album launches, artist Q&As, cultural events and wellness. Its programme has featured artists including Miles Davis, Pixies, Ezra Collective, Steven Wilson, Shygirl, Ed O’Brien, Jorja Smith and Suede, allowing audiences to experience their work in a fully immersive 360° spatial-audio environment.
