Formed in Essex in the mid-1980s, A Primary Industry brought together musicians interested in the darker, more experimental side of British post-punk. The line-up included Ian Cooper on guitar, Paul Hammond on bass, Jemma Mellerio on vocals and clarinet, Guy Waddilove on trumpet and percussion, and Simon Hammond. Their sound moved between post-punk, industrial textures, experimental funk and atmospheric guitar work, with a less conventional approach than much of the indie music circulating in Britain at the time.
The band began releasing records in 1984, including the single 'At Gunpoint', before developing their sound further through releases on Sweatbox, a British independent label also associated with experimental acts such as In the Nursery and Meat Beat Manifesto. Their early material combined tense rhythms, angular guitar lines, unusual instrumental arrangements and Mellerio's distinctive vocal presence. The album 'Ultramarine', released in 1986, brought these elements together, with the group's interest in electronic treatments and studio experimentation becoming increasingly apparent.
As the decade progressed, Cooper and Hammond began moving towards a more electronically oriented sound, working with samplers, sequencers and analogue synthesizers. The transition was gradual, with ideas developed during A Primary Industry sessions carrying over into their subsequent recordings. By 1989, the pair had adopted the name Ultramarine, continuing as a duo and exploring a mixture of electronic music, ambient textures and folk influences.
Jemma Mellerio remained involved during the early Ultramarine period, contributing vocals to their first album, 'Folk', released in 1990 on the Belgian label Les Disques du Crépuscule. After that record, the project continued without her, with Cooper and Hammond developing the more sample-based, rhythmically fluid approach heard on later albums such as 'Every Man and Woman Is a Star' (1991).
