In Barcelona in 1974, J.M. Mestres Quadreny, Andrés Lewin-Richter and Lluís Callejo created the Phonos laboratory, which soon became a pioneering space in Spain in the field of experimentation, composition and dissemination of electroacoustic music. To celebrate Phonos's 40th anniversary, this exhibition offers a journey through the history of electronic music in Barcelona via instruments invented or used in the lab. Synthesizers, reel-to-reel tape recorders, samplers and other old and current electronic instruments are among the displays you can see and hear. Currently Phonos continues to work with the Pompeu Fabra University. During these 40 years of uninterrupted work, Phonos has helped write the history of electronic music in Barcelona.
