Beatriz Ferreyra

In 2015 Ferreyra toured and released an album with Christine Groult, Nahash, on trAce label. The work was commissioned by former of INA-GRM artistic director Christian Zanesi in 2011. The live recording features Ferreyra using "four Revox tape recorders, augmented with an analog matrix and a synchronizer box with self-designed variable speed drives."

Ferreyra has released several albums in the 21st century to critical acclaim. While some of these are re-releases of important earlier works, she has also continued to create new work and perform live (see below, live performance from Festival Zeppelin, 2015), as well as give acoustic composition workshops.

In 1973, Ferreyra was invited to write the music for Fiorella Mariani's film Homo Sapiens (Fiorella is the niece of filmmaker Roberto Rossellini). The hour-long work was completely electroacoustic, for which Ferreyra also did the performing, editing, and mixing.

She worked with Bernard Baschet and his Structures Sonores in 1970, and served residencies in electronic music with Dartmouth College in 1976 and in 1998.

She assisted with Henri Chiarucci's and Guy Reibel's Rapport entre la hauteur et la fondamentale d'un son musical, published in 1966 in Revue Internationale d'Audiologie and Pierre Schaeffer's Solfège de l'Objet Sonore. During this time she also lectured at the Conservatoire National Supérieur de Musique de Paris.

In 1963 she took a position in the research department of the Office de Radiodiffusion Television Francaise (ORTF), working with the Groupe de Recherches Musicales (GRM) directed by Pierre Schaeffer.
