“The Double Life of Bob Dylan” by Clinton Heylin (2021): Title of new biography suggests similar perspective to three 2016 posts here

David Kirby’s review in Washington Post. https://www.washingtonpost.com/entertainment/books/bob-dylan-clinton-heylin-review/2021/05/18/cb42fb8e-b7f9-11eb-a5fe-bb49dc89a248_story.html

Search “Dylan” here. As you can see from the sources I quoted back in 2016, Dylan’s doubling is not a new idea to either me or Heylin. No doubt Heylin adds additional facts and perspective. I don’t know if he includes multiple personality trait.
