The presence of Demme in the director's chair creates anticipation for something as ground-breaking & revelatory as the earlier Stop Making Sense. Instead, Heart of Gold is a tasteful, more retrained, less daring effort, content enough to simply record Young & his musicians engaged in performance. It's very much a film for the fans, with little attempt to build a narrative out of the songs or provide greater context.
I really need to revisit this. I bought and watched it when it came out (2006), but it just left me cold and wanting. But I am double, if not triple the Neil Young fan now I was then, so perhaps being more familiar with his many different styles/moods/incarnations, I would appreciate this film more today. Now I just need to go digging at the bottom of my box of old DVDs........... ;)
