Pip Greasley (b. 1946, Leicester) is a British sonic artist, composer and researcher whose work explores immersive sound, interactive systems, opera, spatial audio and generative media. Working across performance, installation, broadcast and full-dome environments, Greasley has developed an interdisciplinary practice combining experimental music, emerging technologies and audience participation. His work frequently investigates the relationship between sound, movement and human interaction, often anticipating later developments in digital and immersive culture.

Greasley first came to prominence through the groundbreaking 5K Pursuit Opera (1992), produced for Channel 4. The work transformed a competitive cycling event into a live generative opera in which the actions of track cyclists produced music and libretto in real time, ensuring that no two performances were identical. The project received several international awards for innovation, including recognition from Opera Screen, the British Film Institute and the US Golden Gate Awards. BBC programme The Late Show described the work as “the future of opera”.

Throughout the 1990s and 2000s, Greasley continued to develop technologically experimental performance environments and immersive sound works. Last Broadcast (1992–1993), staged at Tate Liverpool, combined live opera singers, robotics and sensor-driven interaction within a geodesic dome installation. Earlier works, such as Planet of the Seas (1971) explored environmental concerns and climate change decades before such themes became widespread within media arts practice.

Since the late 1990s, Greasley has worked extensively with immersive and full-dome audiovisual environments, creating spatialised sound compositions for spherical cinema and large-scale projection systems. Projects include the soundtrack for STARS with the Grammy-winning Nashville Symphony Orchestra, which received Best Soundtrack at the European Festival of Immersive Cinema in 2009, and Astronaut, which won Best Use of Immersive Sound at DomeFest, Chicago in 2008. Other projects, including Total Audio Works, explored navigable and three-dimensional audio experiences within public and interpretive environments.

A long-standing collaborator with Ernest Edmonds, Greasley contributed to the LUTCHI Research Centre and COSTART initiatives at Loughborough University during the early 2000s. Their later collaboration, constructs:conducts (2018), was a generative immersive environment exploring the interaction between sound and colour, premiered at the SATosphere.

Greasley is a Fellow in Sonic Arts at Loughborough University, an Associate Professor at ETH Zurich and an advisory member of the Future Sound Experience at the Ivors Academy. He is currently developing VeloCity: race to zero, a carbon-neutral reimagining of 5K Pursuit Opera, and performs with Sally Hossack as part of the collaborative project COLD WAR.
