“I Shall Prevail” as with other selections also see things in common with Kreator in its delivery and solos. Vocals for Vader are in the Death Metal style but not as cookie monsterish as countless others, more audible. Another quality that Vader use to their advantage if how often they incorporate guitar solos and melodies, separating them from many in the genre.
“The Beast” shows Vader thinking more about the songs as opposed to how brutal everything is while still maintaining the bite for the beast.
