The Tales of Two Musicians "In Search of Blind Joe Death: The Saga of John Fahey" isn't very satisfying as a biography of Fahey, the steel-string guitar wizard, and it probably wasn't supposed to be. But the film, by James Cullingham, does include plenty of Fahey's signature playing. If you didn't already admire his music, you may be searching for more of it after seeing this documentary. Fahey, who died in 2001 at 61, was a self-taught guitarist and composer, as well as the founder of the Takoma Records label. He explored the music of the rural South ("Blind Joe Death" was a fictitious blues guitarist he invented) and other slices of Americana and fashioned them into a sound all his own. Mr. Cullingham tells Fahey's story in fragments, mixing archival clips and interviews with Fahey admirers like Pete Townshend of the Who. Don't look for helpful wheres and whens on the archival material; the intent is more to create a portrait of the man, grainy but with a rich soundtrack. The Fahey film is being shown with "Approximately Nels Cline," a short look at Mr. Cline, the guitarist and composer, as he creates some of his avant-garde work. More conventionally, he is also a member of Wilco. The film, by Steven Okazaki, is not much more than a home video of a recording session, baffling but with an intimate feel.
