Written and directed by Joji Koyama and Tujiko Noriko, Kuro tells the tale of Romi, a Japanese woman living in the suburbs of Paris with her paraplegic lover Milou. Tending to Milou by day and working in a karaoke bar by night, Romi reminisces about a time she and Milou once lived together in Japan with a mysterious ailing man named Mr. Ono. Weaving together personal history, anecdotes, and myths, her stories soon turn ominous. Composed and recorded during the editing of the film in Berlin, the Kuro OST by Tujiko Noriko (with contributions from Joji Koyama, Sam Britton, and Will Worsley), is a crucial and integral part of the film, acting not only as a glue to bind the layers of the film together, but along with the sonic palette of the film's sound design, evokes it's claustrophobic atmospheres and moments of haunting beauty. The music, which in the film is largely heard in tandem to the narrating voice of Tujiko Noriko (who also stars as Romi), is presented and arranged here as a separate piece in its own right.
