Annie Gosfield (born September 11, 1960 in Philadelphia) is a New-York-based composer who works on the boundaries between notated and improvised music, electronic and acoustic sounds, refined timbres and noise. She composes for others and performs with her own group, taking her music to festivals, factories, clubs, art spaces and concert halls. Much of her work combines acoustic instruments with electronic sounds, incorporating unusual sources such as satellite sounds, machine sounds, detuned or out-of-tune samples and industrial noises. Her work often contains improvisation and frequently uses extended techniques and/or altered musical instruments. She won a 2012 Berlin Prize.
