The film is set to music by the Satoko Fujii Quartet with Satoko Fujii on piano, Natsuki Tamura on trumpet, Takemura Hayakawa on electric bass and Tatsuya Yoshida on drums. The quartet reunited last year after a break of 15 years and met with an enthusiastic response: “The rhythm section drives the music forward at breakneck speed, giving it sometimes a more rockish than boppish feel, or something in between. Fujii's compositions are wonderfully complex, with rhythm and tempo changes, long unison lines and brilliantly tight arrangements. Both Fujii and Tamura are in excellent form too. This is music that has a very free feel, but the discipline and mastery of the four musicians shows itself best in the transition between the improvised and arranged moments.”
