I’m pointing out this rerun on Showtime 2 just in case you haven’t yet taken the opportunity to see this music documentary. The recreations of late-Sixties Bob Dylan and the Band hanging around Big Pink are unnecessary, but the step-by-step coverage of the efforts of modern musicians to form songs from some of Dylan’s vintage, forgotten lyrics is a true study in creativity. And as with a similar behind-the-scenes documentary about the making of the Inside Llewyn Davis soundtrack, you come away – at least I did – with a deep appreciation of the skills of Marcus Mumford, especially on the new song “Kansas City.”
