Covenant provides examples of the following tropes:

Drone of Dread: "Modern Ruin Part II", a Hidden Track on Modern Ruin. Another dark ambient piece of theirs is "Cryotank Expansion" from Dreams of a Cryotank. Very Silent Hill-ish.
Epic Rocking / Leave the Camera Running: "Subterfugue for 3 Absynths" is a 42-minute song consisting of a slowly changing noise loop. The aforementioned "Cryotank Expansion" is 26 minutes. "Flux" from Sequencer, in addition to being a total of nearly 12 minutes long, ends with three minutes of the atonal background sounds heard throughout the song proper.
Loudness War: Most everything since and including Northern Light, but especially Modern Ruin. Compare "Figurehead"(1996) to "Judge of My Domain"(2011).
Name's the Same: The Norwegian metal group The Kovenant originally went by the name Covenant as well! Until they were sued by this band, anyway.
New Sound Album: Their first venture into genuine Future Pop was 1998's Europa, consequently the previous two albums suffer Early Installment Weirdness.
