Rotting Christ is in a holding pattern for most of Non Serviam, recording another series of melodic thrash songs with bizarre titles and deeply occult lyrics. The only noticeable difference is a slight change of focus from full-out speed to mid-paced moshers. This new appreciation for restraint and dynamics is especially evident on tracks like "Wolfera the Chacal," "Morality of a Dark Age," and the title track.
