Varèse Sarabande will release the Person of Interest: Seasons 3 & 4 – Original Television Soundtrack digitally and on CD February 12, 2016. The album features the original music composed by Ramin Djawadi.

"The Person of Interest: Seasons 3 & 4 – Original Television Soundtrack is a natural development of season 1 & 2 and showcases the evolution of the show," said Djawadi. "The album contains variations on existing themes, as well as new themes such as the dark 'Brotherhood', 'Martine', and 'Vigilance'."

"The producers wanted the score to reflect the maturing plot line, and for the theme development to coincide with the character development," Djawadi described. "The music differs from the previous seasons because season 3 & 4 present a darker, more evolved story. We record with a 20-piece string orchestra. The size and tone of this ensemble enhances the score and ultimately has become an integral part of the Person of Interest sound. A great fit for this electronic-orchestral score."
