Lakeshore Records will release One and Two – Original Motion Picture Soundtrack digitally on August 28, 2015. The film features original music by Nathan Halpern, his second collaboration with director Andrew Droz Palermo.

"At its heart, One & Two is a fairytale—albeit a chilling one," said Halpern. "Thematically, classic fairytales speak to the most elemental oppositions of childhood: good and evil, love and abandonment, innocence and experience. So the score I created for the film was one of musical dualities: sweet melody and cruel dissonance; natural acoustic instruments and mangled electronics."

"Andrew Droz Palermo is a uniquely poetic director, and he created these very evocative images of the children in nature that I really responded to musically," Halpern described. "In the opening scene, Zac and Eva play in the lake and run in the woods at dusk. Beneath the sounds of the water, I bring in an otherworldly sonic texture to signal that the world of the film is not one of realism, but one of myth and fable."
