Nick Thorburn, who fronted the Unicorns and currently leads Islands, has shared the original score he created for an offshoot of the This American Life podcast called Serial. Serial takes listeners week by week through a nonfiction story that unfolds over the course of a season. The first season follows the unsolved murder of a popular high school senior in Baltimore who is thought to have been murdered by either her ex boyfriend or a classmate, but the details don’t add up. As the host of Serial takes us through the intricacies and complications of this unsolved case, Thorburn’s unnerving soundtrack lingers ominously behind the words of the story. The theme track is especially chilling in the beginning when isolated, deft strikes of a shrill-pitched keyboard draw us in. Listen below.
