large-scale annual festival held in a natural amphitheatre in hampshire, running since 2009. the site is constructed as a fictional city divided into themed districts, each operating as its own independent neighbourhood with dedicated venues, collectives, and programming, adding up to more than fifty spaces across twelve main stages.

music spans reggae, drum and bass, techno, dub, punk, and live performance, distributed across the districts. the built environment of the city is central to the format, with street performance, character-led neighbourhoods, and theatrical architecture running throughout the site rather than sitting alongside it.
