Iara Lee, who previously made the electronic-culture documentary Synthetic Pleasures, turns her camera on the history of electronic dance music, tracing it from early synthesizer and drum machine experiments through the underground clubs and scenes that built house, techno, trance, and industrial into distinct genres. Interviews carry the film: producers, DJs, and fans talk through how these sounds spread from small studios and warehouse parties into a global movement, with each subgenre given its own segment rather than being folded into a single generic story. Lee treats the music as inseparable from the culture around it, following how raves and club nights functioned as gathering points across different countries and social groups. The film spends as much time on the social side of the scene, the sense of connection people describe finding on a dance floor, as it does on the technical evolution of the equipment and production techniques that made the music possible. It closes as a portrait of a genre built by its listeners as much as its producers.
