This is a documentary about hardware synthesizers. The modular synthesizers, to be more precise. It's a thing of the past, yet a bourgeoning movement. Musicians are interviewed and people enthralled, as we're led through the ages of Buchla (who is alive) and Moog (who is dead) and their legacies. Too bad this film did not come with a bigger budget, so that we would actually hear what was made throughout the ages.
