Duncan’s practice utilises both acoustic and electronic forces. His output encompasses concert music, cross-arts collaboration (film, fine art and contemporary dance), computer music and electro-acoustic composition. Recent projects have included experimentation with spectator immersion and the blurring of spatial boundaries between ‘performance platform’ and audience. His work is commissioned, performed and broadcast internationally by amongst others the Arditti Quartet, duoDorT, Fretwork, Galvanize Ensemble, Goldberg Ensemble, Jane Chapman, Juice, London Sinfonietta, Ensemble Okeanos, Making Music, Piano Circus and Tate Modern. Duncan is also an active performer (voice/electronics) and in 2015 formed the trio SounDKard with Sarah Dacey (voice) and Kate Halsall (keyboards).
Duncan is currently Reader in Music Composition at the University of Nottingham, UK.
