War Master is the third album by British death metal band Bolt Thrower. It was recorded at Slaughterhouse studios in September 1990 and produced by Bolt Thrower and Colin Richardson. It was released on Earache Records: Mosh 29 in 1991.Whereas Realm of Chaos was dominated by grindcore based blasts and riffs, this album abandons most of the grindcore influences for a sound that is more strictly death metal.
