Fides Inversa - Hanc aciem sola retundit virtus (2010)
Roman Black Metal using Latin! Sounds promising. The name of the bands means Inverse Faith, The title of the album something like: Just virtue lowers this acuteness.
Also the name of the songs are latin: 01 - decollatio - decollation/ decapitation; 02 - suicidium - suicide; 03 - homicidium - homicide; 04 - algolagnia divine - mmh, I'm not sure, but álgos means pain/ sorrow/ suffering in ancient greek and lagneía lust/ excess. Makes sense.
Unfortunately I don't have the lyrics, because the bands says (on their myspace profile) that there is a certain concept and idea behind the songs.
So there remains some play in the album's title: acies (accusative: aciem) means the sharpness of a sword, the acuteness of actions/ words or thoughts. Also virtus is an important word: during Roman times it stood for the features which a Roman needed to be a man: bravery as a soldier, efficiency and competence as a politician. In christian times virtue was of course something totally different, more the subjection to catholic rules and commandmends.
