Annie Gosfield (born September 11, 1960 in Philadelphia, Pennsylvania) is a New York composer who specializes in using detuned or out of tune samples and industrial noises. Her work often contains improvisation and frequently uses extended techniques and/or altered musical instruments.Her work includes large-scale compositions, chamber music, electronic music, video projects, and music for dance. She uses traditional notation, improvisation, and extended techniques to explore a sound world that eliminates the boundaries between music and noise. Her music is often inspired by the inherent beauty of non-musical sounds, such as machines, destroyed pianos, warped 78 rpm records, and detuned radios. She often works in close collaboration with musicians, in order to emphasize the unique qualities of each performer. Gosfield's compositions have been performed internationally by The Bang on a Can Allstars, Agon Orchestra, Joan Jeanrenaud, Fred Frith, Felix Fan, Roger Kleier,
