Settle down Tony..I mean IT.
War was the result of a drunken night deep within the Abyss studios, home of Peter Tagtgren. His friends from Abruptum and Dark Funeral spent the night ranting about how they should pay to have Varg killed. They would make a album of primitive, hateful Black Metal with any profits going to The True Satanic Horde ( a hobby of IT's) and to finance the murder of Vikernes.
So if you like hateful, angry BM with lyrics about Satan, war and Satan ( plus some questionable, PC baiting lyrics in the track "I Am Elite") then this should be right up your alley. I like it for its single minded hatred and refusal to slow down. I think that's a fair reason.
