Ceremonial Oath was one of Sweden's pioneers of melodic death metal, a style that became synonymous with Swedish death metal.  "The Book Of Truth" from 1993 does not really match the usual melodic approach many bands from Gothenburg scene established between the heydays of the scene from 1994 to 1999. Being neither pure Gothenburg-ish melodic death metal nor typical old-school Swedish death metal in the Stockholm vein, but more a fine mélange of both worlds spiced up with some technical finesse a la MORBID ANGEL and NOCTURNUS, "The Book Of Truth" has justly become a real classic of unique death metal throughout the years. Still, to this day, the sound of CEREMONIAL OATH has remained surprisingly fresh and unique.
