Musica Elettronica Viva (MEV) is a live acoustic/electronic improvisational group formed in Rome in 1966 by Alvin Curran, Richard Teitelbaum, Frederic Rzewski, Allan Bryant, Carol Plantamura, Ivan Vandor, and Jon Phetteplace.
They were early experimenters with the use of synthesizers to transform sounds: a 1967 concert in Berlin included a performance of John Cage's Solo for Voice 2 with Plantamura's voice transformed through a Moog synthesizer.
