Ultramarine are a British progressive dance and electronic music duo, formed in the early 1990s by Paul Hammond and Ian Cooper. Hammond and Cooper first worked together in the band A Primary Industry during the mid-1980s. Following the split of this band, they formed Ultramarine and released the album Folk in April 1990. The 1991 album Every Man Every Woman Is A Star was released to rave reviews and the band signed to Blanco y Negro from where they released the folk-influenced follow-up United Kingdoms featured Robert Wyatt and the jazzier Bel Air. After releasing a compliation of old material the band called it a day.
