The title of the album is a latin phrase that means "About the mysteries of Lord Satan". This is what you need to expect when listening to this crude and threatening record! The album was released after the death of Mayhem's guitarist, Euronymous (Greek for Prince of Darkness", killed by the bass player, Count Grishnackh,whose contribution on this album was dubbed over. Mayhem were the founders of black metal as we know it today and this was supposed to be the definitive statement on the ferocity and darkness enveloping the new Norwegian scene.
The first track is Funeral Fog with haunting vocals by Attila, now singer with Aborym, whose vocal style is very dark and original; actually he sounds like a wounded madman, spewing rage and depravity. The rest of the tracks also are very impressive, conjuring up a very dark atmosphere that sucks you right in. Hellhammer's drums also are very impressive, thundering away together with the bass. The only negative note can be made about the production on this album, even though its lo-fi, I suspect, 4-track recording in itself helps with the atmosphere of a pagan rite. A great, great album and a must-buy for any black metal fan!
