"Sumerian Daemons" is a multi-layered beast of an album that takes Death Metal and mixes it up with touches of classical music and various electronics such as Industrial which results in this album. There is usage of samples used in the recording as well as various riffs from the guitars and classical vocals by Natalie Rossoulis and a choir which creates the atmospheric feel of the album. The songs go from fast (Unbeliever, Red Code Cult) to slow (The Virtues of the Beast) to even melodic (Infernal Sun, Magic Loves Infinity) and some change gears (When All is None) which keeps the listener on his toes, depending on the mode of said listener. The main male vocalist, Seth (Spiros Antoniou) has a deep growl which is clear and works because it is the rough to Natalie?s opera-like smoothness when she sings, as well as the music itself. The lyrics themselves are well thought out in detail.
