I believe documentaries about music artists and their projects can sometimes be very difficult to succeed in since they're such different forms of creating; one is recording and using what you have available to create or reveal a narrative, while the other is actively creating through experimentation surrounded by themes, topics, specific expressions, etc. But, this documentary does both beautifully, connecting the two in a unique way. Watching the film I felt I could read the music score actively while the scenes played out, attaching what felt like the intention behind the music to what was on the screen. This created an overall cohesive narrative that absorbed you in his world. But not only just visually, emotionally too.
