i be greatly disappoint by the quality of this documentary . the content be poorly produce and very poor quality video and and especially awful audio . there extremely little about how bruce haack produce his music and virtually no example of direct connection to later and contemporary electronic music . the interview of people who know bruce haack be ad hoc mostly inarticulate mumbo jumbo . too much yak and not enough haack . although i have a serious personal interest in electronic music and have a high than average attention span and even for slow and or or difficult subject matter and i fell asleep while watch this documentary and have to review it to see the part i sleep through . if you watch this and make sure that you be set up and before view and like alex in a clockwork orange . bruce haack deserves much good than this . shame on the producer and director .
