Maybe it's the Midwest in me, but I am predisposed to folk and blues - I often find myself turning this film on in the background just for the performances and variations on some genre staples (Mumford's version of "I Was Young When I Left Home" is a surprise). Along those lines, the film acts as a kind of fly-on-the-wall masterclass in producing: seeing T-Bone fill a room and focus the talent towards creativity is a privilege.
