Theory of a Deadman is a hard rock quartet from North Delta, British Columbia, formed when the members began jamming together in high school. The band consists of Tyler Connolly, Dave Brenner, Dean Back, and Joey Dandeneau. Known for their sky-high hooks, thick riffs, rumbling grooves, and razor-sharp humor, they've established themselves as an unapologetic rock force over the past two decades, earning multiple platinum certifications and topping the Billboard Hot Mainstream Rock Tracks Chart three times.
