Their work was primarily released as cassettes and CDs on Fell's label Bruce's Fingers, including Bogey's and the group's only studio album, foom!
[4] Other groups in which Fell was a member included the free jazz trio Badland (led by saxophonist Simon Rose; initially the drummer was Mark Sanders, with Steve Noble subsequently taking over the role), the improvising string and percussion ensemble ZFP (with Carlos Zingaro, Marcio Mattos and Mark Sanders), and SFQ, a quartet/quintet with changing membership, though clarinettist Alex Ward has been a constant.
In sharp contrast to the uproar of Hession/Wilkinson/Fell, the trio IST (with Rhodri Davies and Mark Wastell) was one of the seminal groups in the development of the ultra-quiet aesthetic now generally called "EAI" or "electroacoustic improvisation".
Free improvisation, rock and jazz all form key parts of the musical language; one section of Compilation IV even includes a simultaneous homage to Karlheinz Stockhausen and Henry Mancini.
While virtuoso players such as Evan Parker and John Butcher were essential to the projects, Fell often deliberately made use of amateur or student musicians, too, not as a makeshift but as an intentionally democratising and less predictable element.
