The sound of "Thousand Swords" is very distinctive, with melodic guitar riffs and fast, aggressive drumming. The album's production is quite raw and primitive, giving it a very atmospheric and dark vibe. The lyrics of the songs focus on pagan mythology and European history, with references to Odin, the Middle Ages, and the fight of the European peoples against the invaders. It is a band that has influenced many other musicians in the black metal scene and is considered an important exponent of the genre.
