A still from the Nazoranai documentary.

For the third chapter of Sam Stephenson and Ivan Weiss’s “Big, Bent Ears: A Serial in Documentary Uncertainty,” we’re premiering their documentary on Nazoranai, an experimental improvisation trio. All the interviews and recordings come from last year’s Big Ears Festival, in Knoxville. The writer Ben Ratliff, who appears in the film, has said that “it’s good for the brain to watch this.” We wholeheartedly agree. Watch the documentary here.
