Elektro Moskva is an essayistic documentary about the Soviet electronic age and its legacy. The story begins with the inventor of the world's first electronic instrument, Leon Theremin, unveiling the KGB's huge pile of fascinating devices, some of which were musical. They all came into existence as a by-product of a rampant defense industry. Nowadays, those aged and abandoned 'musical coffins', as solidly made as a Kalashnikov, are being recycled and reinterpreted by the post-Soviet generations of musicians, sound collectors and circuit benders. The story of the Soviet synthesizers as an allegory to the everyday life under the Soviet system: nothing works, but you have to make the best out of it. An electronic fairy tale about the inventive spirit of the free mind inside the iron curtain- and beyond.

After escaping Russia's communist revolution, Léon Theremin travels to New York, where he pioneers the field of electronic music with his synthesizer. But at the height of his popularity, Soviet agents kidnap and force him to develop spy technology.
