retrograde structures, &c), as well as many other techniques: extensive studio layering, overdubbing and reordering of material (so that seemingly "live" performances may be the result of carefully edited-together improvisations and/or notated material), and use of aleatoric techniques to "degrade" or distort precomposed structures into new shapes. 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. The cast of musicians drawn on for these pieces usually included a mix of classically trained players, jazzers and free improvising musicians, as well as wild cards like the noise guitarist, Stefan Jaworzyn. 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. Fell died on 28 June 2020. Other large-scale composition projects included: his compositions for The London Improvisers' Orchestra (Papers, Happy Families, Köln Klang, Ellington 100 (Strayhorn 85), Morton's Mobile, Too Busy and Three Mondrians) (1998-2004) Kaleidozyklen, a 60-minute piece for improvising double bassist and orchestra (2000) Thirteen New Inventions, a major solo piano piece commissioned by Philip Thomas (2005) the concert-length BBC Radio 3 commission, Positions & Descriptions (for 18 musicians and prerecorded materials), premiered at the Huddersfield Contemporary Music Festival (2007) a one-hour suite for sextet, The Ragging Of Time, commissioned by the Marsden Jazz Festival (2014) Discography (selection) composition projects SIMON H.
