For the first scene where it is set in the woods we will use this music, we used 'Soda' by the Cinematic Orchestra. It works well with the voice over we are going to use and has a mysterious feel to it which works well with the theme we are going to use.
For the second scene after the main title (of rewound scenes back to the beginning of the film) we used 'Breathe Me (instrumentral version)' By Sia.
