O Yuki Conjugate (OYC) are an English post-industrial/ambient musical group founded in 1982 in Nottingham by Roger Horberry and Andrew Hulme and still - intermittently - active today.
Their music has been variously described as 'ambient', 'fourth world', 'ethnic', 'tribal' and 'dark wave'; the band prefer to call it 'dirty ambient'.
Previous members include Clare Elliot, Tim Horberry, Malcolm McGeorge, Dan Mudford, Pete Woodhead and Rob Jenkins, with Joe Gardiner contributing sax.
Originally inspired by the spirit and sound of post-punk, they soon started pioneering their own brand of ambient at a time (early 80s) when few people were interested in such a low-key approach.
In May 2017, following a lengthy period of hibernation (a regular feature of the band's career), OYC released a new album called 'Tropic', essentially two long pieces generated out of material recorded during the Equator sessions almost 20 years earlier.
