Set between a rural Appalachian town and the mystical world of witches and warlocks in the Smoky Mountains, this musical follows the relationship between Barbara Allen, a human girl, and John, a young witch. Their connection challenges the divisions between their communities, which are shaped by suspicion, tradition, and long-held fears. As they attempt to build a life together, the consequences of a supernatural bargain made “by the dark of the moon” threaten their future. The score blends country and bluegrass influences with rock elements to reflect the cultural and supernatural forces shaping the story.
