This documentary is a true asset to mankind. Robert Moog was a great man. One of my heros, and to me he is an absolute legend. This documentary goes through the times, places and artists when the synthesizer was invented, and what took place, also little interesting things from Moog, such as he said he could "feel" what's going on inside electronic equipment(or something along those lines). Of course covers the man who invented the synthesizer, who is a beautiful person IMHO. You can feel it in his voice alone (I can anyway) :)
