Hessian began in 2008 when the Horrible Twins, Angus and Salli, created the form and essence of the Black Magic Boogie Ritual. Planting various ingredients in a dung heap they called into being an otherworldly rhythm section whose throbbing pulse causes trance and hysteria. Their followers are to be found committing sordid acts in the low and unwholesome rock clubs of the world, driven to unheeding frenzy by songs like "Cloven Lady" and "Funeral Disco." Avoid them like the plague.
