"A bright celestial body rises on the firmament of Skyggeraich. The Specter and Morden Demstervold have woven their dark magicks into two promotional demos of grandiose Black Metal art. Tirgûl's journey continues as the contours of the realm get sharper, ancient truths unveiled and the underworld forces gather for attack on the heavens above, demanding a victorious star." (from their bandcamp)

I have no idea what all of that means but it sounds like good mid-paced European black metal with keyboard accents (not symphonic) like old Graveland or Infernum.
