Nocturnal Emissions is Nigel Ayers's sound art project that has released numerous records and CDs in music styles ranging from electro-acoustic, musique concrète, hybridised beats, sound collage, post-industrial music, ambient and noise music. Their sound art has been part of an ongoing multimedia campaign of guerrilla sign ontology utilizing video art, film, hypertext and other media, particularly collage.^[1] Nocturnal Emissions were depicted by the novelist Stewart Home.

The project was initiated in Derbyshire in the late 1970s by Nigel Ayers (b. 1957), a former art student who, during the period, lived in London, together with collaborators Danny Ayers (b. 1964) and Caroline K (1957–2008). Since 1984 Nocturnal Emissions has continued mainly as Nigel Ayers' solo project.

In 1979, Nocturnal Emissions founded Sterile Records. Sterile Records’ approach was a combination of the experiments of musique concrète and Fluxus combined with the critical eye of conceptual art and the spontaneity and energy of punk rock. The dark humour of industrial music and the incomprehensible nonsense of various ultra-leftist political fractions were an essential part of the mix. Sterile Records used both commercial and non-commercial media to deliver anti-capitalist messages, multi-coloured noise and information overload. The label was effectively dissolved in 1986, when Ayers founded Earthly Delights.^[2][3][4]

In 1990–92, Nocturnal Emissions collaborated on Butoh dance performances in Europe and the United States, with the Japanese choreographer Poppo Shiraishi. Around this time Nocturnal Emissions' Situationist-influenced practice became increasingly informed by magick, stone circles, techno–shamanism, neo-paganism, animism and Fortean research. There were many collaborations on animated films by Mancunian TV director Charlotte Bill. Bill was never an official member of Nocturnal Emissions but admits to being one of the legion of members of The Fall^[5]

Nocturnal Emissions were later to be associated with the Kernow section of the Association of Autonomous Astronauts^[6]
