Beatriz Ferreyra is a pioneering electro-acoustic composer from Argentina. Her complex, imaginative works transform natural and everyday sounds into haunting yet familiar soundscapes. During the 1960s, she worked at the Groupe de Recherches Musicales (GRM) along with founder Pierre Schaeffer, and lectured at the Conservatoire National Supérieur de Musique de Paris. She has since composed music for film, radio, television, and music therapy, and performs commissioned works for concerts and festivals. She largely worked using tape before switching to computer-based compositions during the late '90s. Her music began receiving increased recognition around the time GRM Works, containing pieces dating back to the late '60s, was issued in 2015. Numerous recordings have appeared since, including the 16-channel piece Senderos de luz y sombras (2023) and collections of compositions from throughout her career, including Echos + (2020) and UFO Forest + (2023).
