As someone who grew up with Dylan starting in 1963, this seems superfluous, esp while he’s still alive and while all of his recordings are available for anyone to trace his career by actually listening to them. But I understand why this could be a good path for younger folks to understand the impact that Dylan had on popular music. I just hope they do this right: there’s a special place in cultural hell for the filmmakers if they blow it.
I think a definitive, extensive documentary with all of the live performances might be time better spent…
