Oscar nominated and Grammy-winning composer Mark Isham teams up with his frequent collaborator, director Gavin O'Connor, to create a score that explores a world of duality and intrigue for the upcoming action thriller The Accountant. Opening in theatres on October 14, 2016, it follows Christian Wolff (Ben Affleck), a math savant with more affinity for numbers than people.

For the film, Isham created a hybrid score, which includes a 78-piece orchestra, choir, solo cello as well as 27 feet of Steinways (three pianos). Isham explained that writing the score was a massive undertaking, but the challenge was necessary to tell the story. Tapping into his diverse musical talents, he provides a score that traverses between the structured world of accounting and the danger of the central character's dual life.

"It is the most diverse score I have ever done, but it holds together through thematic unity—the score is based on mathematical equations and patterns," Isham states. "Despite the lush orchestration and massive amounts of customized electronica, the music is not overly dramatic. The main character of The Accountant is a mathematical prodigy, and lives in the world of numbers and numeric patterns. Therefore, I wanted the music to reflect that. Part of the score was created using a series of simple patterns with enough randomness to create texture and nuance. As an example, two notes out of every three would be played, then 5 out of 7, etc. all juxtaposed together, then randomized with competing tempos!"

The Accountant - Original Motion Picture Soundtrack will be released digitally October 7, 2016.
