Lakeshore Records will release the Swiss Army Man - Original Motion Picture Soundtrack digitally on June 24 and on CD July 8, 2016. The album features the film's unique score by Andy Hull and Robert McDowell of Manchester Orchestra. The first single Montage, with vocal performances by the film's stars Daniel Radcliffe and Paul Dano, was released on June 3.
The directors challenged Hull and McDowell to write a score using the protagonists "limited resources" as a guide. They were charged with writing a score using only sounds that either existed in the natural environment that Manny and Hank found themselves in, or sounds that a body could make for the bulk of the story. The score is almost exclusively minimalist and a cappella until it erupts into a traditional orchestration for the film's final scene. "The premise of the movie was always about this guy in the woods and we ourselves intended to use only what was available to us there," Scheinert explained.
"Andy is really good with his vocal melodies and harmonies; he has great control over his voice," said Kwan. "The movie was going to require nothing but vocal harmonies, and Robert had the technical chops. Between the two of them, they made a really efficient and talented musical team."
"We knew how to make music with instruments, but it was intriguing to us to conceive orchestral-sounding music with only our voices," said Hull.
"It was exciting to learn how to complement another piece of art with something that sits in the background," added McDowell. "The Daniels wanted us to go big and let the music overtake key scenes. Finding the push and pull as we set about building these grand musical moments was a true artistic challenge."
