What I always loved of Hades from Norway is their approach to the Viking/black metal. Before changing into Hades Almighty, their style was great for this reason: they were always able to mix perfectly the most epic and obscure influences with a raw form of black metal. Yes, black metal. So, if you're into the harmless and annoying symphonic/epic/Viking Finnish bands, stay away for this because it's too black metal oriented in the production and sounds. They were heavily influenced by Bathory in the period between "Under The sign of the Black Mark" and "Hammerheart". So, already form here we can understand that they are not into sugary, boring, fantasy melodies. We have no flutes, medieval instruments or feasting noises...the main point is to create epic but obscure melodies. The guitars and few keyboards are the maximum expression of their sound. Everything is quite bare-bone, musically talking and it's great just like that.
