Bill Gilonis (born 1958) is an English guitarist and composer.
He co-founded the gritty experimental rock group The Work in 1980 with Tim Hodgkinson. The group was active intermittently until 1993, recording four albums and touring extensively, including in Russia, Japan, Finland, Yugoslavia and Switzerland. Gilonis has also worked as a producer, sound engineer and/or musician with (among others): Robert Wyatt, News from Babel (Chris Cutler, Lindsay Cooper, Zeena Parkins, Dagmar Krause), David Thomas, Peter Blegvad, Ut, Lindsay Cooper Film Music Group, Hail and The Hat Shoes (with Catherine Jauniaux, Tom Cora, Charles Hayward, and others). Other projects include: writing and recording the music for Frida Béraud’s one-woman theatre piece, Aus den Haaren gezogen; a collaboration with Anja Burse on Wild Thing, an audio-visual installation piece; and a multi-media piece for the Val de Travers exhibition about Absinthe in Neuchatel, Switzerland (with Luigi Archetti, Jeroen Visser and Julien Baillod).
He has been living in Zurich since 1993 where he has mixed and/or produced CDs by Swiss bands such as No Secrets in the Family, The Jellyfish Kiss and Lödig. His most recent recordings have been Zürich-Bamberg (Ad Hoc, 2008), a CD of electroacoustic compositions (together with Canadian composer Chantale Laplante), and Calvary Greetings by the Anglo-Dutch-American band Stepmother (with Lukas Simonis, Jeroen Visser and Dave Kerman) - a reunion of an 80s band that never existed (but should have): twangy guitars, nifty keyboards, zany drumming, vocal histrionics à la The Rutles (well, sort of), lop-sided rhythms, regurgitated spam lyrics.
In 2009, together with Alex Julyan, he published a book "Lost in Translation", on Lost & Found Publishing.
