Jazz aficionados should enjoy this German documentary about Blue Note Records, one of the most important institutions in the history of the genre, as it features spirited interviews from such venerable figures as Sonny Rollins, Rudy Van Gelder, Herbie Hancock, and George Benson. The film also tells a moving story of the longtime friendship between Blue Note cofounders Alfred Lion (nee Loew) and Francis Wolff, two Jewish men who bonded in Berlin over their mutual love of jazz and became business partners in New York after both fled the Nazi regime. Director Eric Friedler emphasizes how Lion and Wolff’s principled management of their record label stemmed from their appreciation of the music they recorded; former collaborators fondly recall the familial atmosphere around Blue Note under the cofounders’ leadership, and they’re also quick to note that every recording artist at the label was decently paid. Setting aside some distracting computer-animated sequences, this is lovely nonfiction filmmaking. In English and subtitled German.
