There’s an ancient Japanese legend in which a horde of demons, ghosts and other terrifying ghouls descend upon the sleeping villages once a year. Known as Hyakki Yagyō, or the “Night Parade of One Hundred Demons,” one version of the tale states that anyone who witnesses this otherworldly procession will die instantly—or be carried off by the creatures of the night. As a result, the villagers hide in their homes, lest they become victims of these supernatural Invaders.

Such is the inspiration for the latest album from Earthless. “My son is really into mythical creatures and old folk stories about monsters and ghosts,” bassist Mike Eginton explains. “We came across the ‘Night Parade of One Hundred Demons’ in a book of traditional Japanese ghost stories. I like the idea of people hiding and being able to hear the madness but not see it. It’s the fear of the unknown.”
