Sylvia Hallett studied music at Dartington, and then spent two years studying composition with Max Deutsch in Paris. She now works both as a composer and as an improviser, and has had pieces performed in Britain and Europe. She has played in many international festivals since the late 1970s, working with several well-known and respected musicians, including Lol Coxhill, Maggie Nicols, Phil Minton, Evan Parker, and the groups Accordions Go Crazy, LaXula, British Summer Time Ends, Arc,The London Improvisers Orchestra, and the London Hardingfelelag. She also performs solo, (eg. in Museo Wolf Vostell, Caceres), and in duo with Clive Bell, with Mike Adcock, and with Anna Homler. Projects with various theatre and dance companies include collaborations with the dancer/choreographers h2dance (Hanna Gillgren and Heidi Rustgaard), Miranda Tufnell, Emilyn Claid, Jacky Lansley, Lost Dog, and Eva Karczag, and the live art puppeteer Nenagh Watson, and Suffolk-based Wonderful Beast. She has performed and musically directed the music of Adrian Lee in world tours with the Young Vic's highly acclaimed "Grimm Tales", and The Royal Shakespeare Company's productions of "Comedy of Errors", "Tales from Ovid" and "Canterbury Tales".
Sylvia has released three solo CDs, two on the MASH label, which contain songs, improvisations, and tape collage pieces derived from her compositions for theatre and dance. Her 3rd solo release, White Fog on the EMANEM label features the bowed bicycle wheel. Commissions include incidental music for several BBC Radio Plays, most recently Two Men From Delft. Her work on Virginia Woolf's Kew Gardens received favourable reviews for its innovative use of voice and sound manipulation.
