There are at least 32 stick-with-you moments in director Sam Green’s inventive and contemplative documentary 32 Sounds. In the live version of 32 Sounds, playing July 27 at the Exploratorium, Green will narrate the film in person. In all screenings, some portions of the film are heard collectively in the theater while others come via binaural headphones handed out before each screening. 32 Sounds plays at select Bay Area theaters July 27–30.
