"Imperial Doom" with it's raw brutality represented a more modern aspect of the genre, through the basic old school death metal themes, when aggressive hammering wasn't enough anymore. The themes turned into a more complex direction, not the feeling was in focus, but the mix of intensity and technical knowledge. This was usual in the second and ending period of the golden age of death metal. The search for some diversity was more like instinctual than scheduled, some bands turned melodic, others played more technical or progressive. Monstrosity was on the borderline of that change and reached the most suitable level of musical brutality for themselves in a bit more techinal way.
