Illusion were a British band formed in 1977. They released two albums, Out of the Mist and Illusion on Island Records. Their music was classically-inspired, sophisticated, and polished. The band undertook a number of tour dates but found their style of music out of fashion with the rise of punk rock and disbanded.Illusion were intended to be a reunion of the original line-up of Renaissance (whose second album was titled Illusion), but singer and guitarist Keith Relf died before the project was realised. Jim McCarty moved from drums to play acoustic guitar and share vocals with Jane Relf, while Eddie McNeill replaced him on drums and John Knightsbridge took Keith Relf's place as guitarist following his death.In 2001 the four core members issued an album of new material under the name Renaissance Illusion, but did not play any concerts in support of the album.
