Mega Tip! ** 290 Copies only. LP In gimmick poster fold-out sleeve **  Susana Baron Supervielle was born in Buenos Aires in 1910, but she lived in Brazil most of her life. Creation with electroacoustic means represented one more step in her search for renewal and a new articulation of her triple cultural horizon articulated between São Paulo, Buenos Aires and Paris. The results open a new dimension in the interstices of the sound montage. Susana had been a follower of Pierre Schaffer and his peers in the Groupe de Recherche de Musique Concrète from Paris since they began in the early 1950s. Baron Superveille’s catalogue of works, as selected by the artist herself, shows nine compositions for magnetic tape. With one exception (1977’s Continuo variante), the pieces are in the personal archives of the composer filed in the Archivo del Instituto Nacional de Musicología “Carlos Vega”, in Buenos Aires, which depends on the Ministry of Culture of the Republic of Argentina. This edition on Wah Wah Records is a coproduction with the Instituto Nacional de Musicología “Carlos Vega” and recovers all the available electroacoustic works composed between 1974 and 1980. While most of the collected works premiered in both Buenos Aires and São Paulo on dates close to those of their composition, there are not any previous known releases of these recordings, so this LP is not only an exception, but also a novelty.
