Jan Dukes De Grey was a progressive folk-rock band from England, formed in Leeds in December 1968 by Derek Noy and Michael Bairstow. The band released their debut album Sorcerers in 1969 on Decca Records. In 1970, drummer Denis Conlan joined, evolving the band's sound to become more progressive. They opened for acts like Pink Floyd and The Who but saw modest sales with Sorcerers. In 1971, they released their second album, Mice and Rats in the Loft, on Transatlantic Records. Despite tepid sales, the band continued performing locally until 1973 when Bairstow left. By 1974, the band changed its name to Noy's Band and released a single before disbanding in August 1975. In 2010, their previously unreleased album Strange Terrain was issued by Cherrytree Records, marking a moderate revival of interest.
