Sure, there are lots of reviews that concentrate on the sections that revolve around the African - Euopeans and Americans that interrupt the recroding session or the Rolling Stones' Sympathy for the Devil. But, this is just a small part of an amazing and beautiful record of a process that created a song that will last for generations.
Watching the rhythm section work out the song, Mick working out the lyrics, Keith conducting the whole thing, Brian Jones playing remarkable keyboards, reminds us of the process of production. It took time. It took failures and it became an amazing song.
Besides that, the film is so beautifully shot is looks like it came out of an 21st century design magazine.
And please don't ignore the digressions. It is (in my humble opinion) about the appropreation of black culture by whites and white culture by blacks. An interesting diversion when you think about 1968 and Europe and the Americas. We all switch and use and sometimes it makes beautiful music.
This is an important film that should be seen by anyone going into a studio to record a song that will be remebered forever.
