Unfurling from a core of rhythms that range from hypnotic to crippling, Fire Shepherds, the first from this team-up between Mark Kyriacou and Karl Webb-of the stunning Super Numeri, an equally puzzling powerhouse of sound-is a serious dazzler. Whether it’s the Hitchcockian grind of “Safe Self Tester,” the prog-dance freakout of “Meet Dad,” or the sprawling two-parter “Tabernacle,” the cinematic Fire Shepherds is an edge-of-the-seat hell ride through the sonic spectrum. Have fun. I envy you already.
