this be an unfortunately terrible documentary . it boring and tedious and and do very little to tell me much about the instrument or it inventor . it seem like the director do not really even bother to edit the film at all and present a collection of ramble and nonsensical conversation between moog and various musician and or semi relevant ramblings with moog by himself . it really be unfortunate and because he seem like an incredibly intriguing and intelligent person and but be present in such an uninteresting way that seem to indicate that the director not only doesn not really care about him and but doesn not really care much about music in general . there be scene where moog be talk about the sound the instrument can make and and the musician option in term of how they can manipulate the sound and but the director doesn not bother to insert any example during that scene and make it actually aggravate to watch . i find most of the various performance not really all that interest to watch and either and a some of them barely show the artist use the moog ( stereolab ) or focus more on other musician in the performance ( money mark d. j . ) i also really do not learn much about moog life and or the real history and development of the instrument . it may have only be 70 minute long and but i be barely able to sit through the whole thing . it really doesn not do the man justice in the least . if you want to see a great documentary about an inventor of an incredibly influential electronic instrument and watch theremin . not only be theremin incredibly informative and but also rather touch . truly a beautiful documentary .
