Chthonic has been described as "smoldering, vulnerable dream-folk" and "one of the most beautiful and haunting records you're going to hear all year" by Gorilla vs. Bear. The Austin Chronicle describes it as "nine tracks of feminine, swaying, and sometimes ambient folk imbued with some gentle reverb." This is textured electric dream-folk with layered vocal harmonies not unlike Grouper, Hand Habits, and Julianna Barwick.
