The album consists of Regina Spektor's cover of "My Guitar Gently Weeps" plus score by Dario Marianelli (for reference, he composed the soundtracks for The Brothers Grimm (2005), Pride & Prejudice (2005), Atonement (2007), and Anna Karenina (2012); for the last three of these he received Oscar nominations for Best Achievement in Music Written for Motion Pictures, Original Score. In 2008, Marianelli won both an Oscar and a Golden Globe for the score of Atonement).
Plot: the story is set in ancient Japan, where a young boy named Kubo cares for his sick mother in a village. A spirit from the past turns Kubo's life upside down by re-igniting an age-old vendetta. This causes all sorts of havoc as gods and monsters chase Kubo who, in order to survive, must locate a magical suit of armor once worn by his late father, a legendary Samurai warrior.
