Jack Vaul’s back, and this one’s cooked. We’re talking Unit 731 — Japan’s so-called “research lab” that was really a house of horrible, human experiments. Strap in and try not to lose a limb, this story’s darker than dark face.

Singer/Songwriter

Jack Vaul is a rapper and songwriter who’s been part of the Oldmate & Josh orbit since the very beginning. One of the podcast’s original guests and a longtime mate of the show, Jack brings the same raw honesty and creative edge to conversation that he brings to his music. With a sharp ear for storytelling and a knack for turning real life into lyrics, he’s the kind of artist who keeps things authentic — no polish, no pretence. When Jack’s in the room, the conversation usually drifts somewhere interesting, somewhere funny, and occasionally somewhere a little bit dangerous… exactly how we like it.
