Extensive ovierview on Spanish electronic music pioneer Edoardo Polonioa, containing a biographical account filmed by Javier A. Bedrina (video) and a audio dvd with a selection of 48 electroacoustic works composed between 1969 and 2014. The total length is nearly 10 hours (!) and it has an extensive booklet with this that details in alphabetical (rather than chronological) order these pieces, in English and Spanish. Eduardo Polonio has been one of the key figures of Spanish music since the late 1960s, especially as a pioneer in the field of electroacoustic music. He was a member, with Luis de Pablo and Horacio Vaggione, of Grupo Alea Electrónica Libre (1970-1972), the first Spanish group to play electronic music live, and he has been one of the main figures of Barcelona's Laboratorio Phonos studio since 1976. He was also a founding member and president, between 1988 and 1994, of Spain's Electroacoustic Music Association. In 1994 he received the Magisterium award at the Grand Prix International de Musique Électroacoustique in Bourges, France. His deeply personal body of work has often gone beyond recorded sound to establish a dialogue with physical space and other artistic creations, as exemplified by his numerous collaborations with sculptors, video artists, painters, experimental filmmakers, and stage designers, and his own work in the field of installation art. In 1976 Polonio moved to Barcelona and became involved with the city's Phonos Electroacoustic Laboratory, meeting composers Andrés Lewin-Richter and Josep María Mestres-Quadreny.
