wisdom teeth extracted, she immediately joined the band in the studio to record their second album Unrest (1974). However, following their European tour supporting Captain Beefheart, the group reorganized themselves and asked Cooper to leave, performing as a quartet on their Scandinavian tour of September 1974. But she still continued to guest on their albums and by February 1975 she rejoined the group again and remained a permanent member until they split up in 1978. From 1977, Cooper became one of Henry Cow's principal composers and contributed a number of compositions to their repertoire, including half of their final album, Western Culture (1978). The nature of the group enabled her to expand her musical horizons and experiment with new ideas. She also started playing soprano saxophone and piano during this period and began exploring improvisation techniques. Henry Cow toured Europe extensively, exposing Cooper to a variety of musical styles and musicians, all contributing to the development of her musical career. Other projects Cooper's work with Henry Cow attracted the attention of musicians from around the world and she had no shortage of performance and recording opportunities. Late in 1977, during Henry Cow's last years, Cooper co-founded the Feminist Improvising Group with Sally Potter, Maggie Nichols, Georgie Born (from Henry Cow) and Irène Schweizer. An international group of women improvisers, they toured Europe on and off between 1977 and 1982. She also kept a foot in the Canterbury scene by re-uniting briefly with Comus and playing on their second album, recording with Steve Hillage, and contributing to Hatfield and the North's The Rotters' Club (1975) album. After Henry Cow, Cooper joined National Health (whom she had already sat in with), but left soon after when Dave Stewart departed. In 1980 she recorded her first solo album Rags, a song-cycle about sweatshops in Victorian England, with Chris Cutler, Fred Frith and Georgie Born (all from Henry Cow) and Phil Minton and Sally Potter. In 1982 Cooper formed her own group, The Lindsay Cooper Film Music Orchestra, in which she wrote and performed film and TV scores, including the soundtrack to Sally Potter's debut feature film, The Gold Diggers (1983), starring Julie Christie. During the 1980s, she toured the United States with David Thomas and played in various bands in England led by jazz composer Mike Westbrook. In 1983 Cooper collaborated with Chris Cutler and formed the English avant-rock group News from Babel,
