Deathspell Omega is a French black metal band. Their lyrical content deals primarily with Satanism on a metaphysical level – as the band has stated that "all other interpretations of Satan are intellectually invalid" – and other various theological topics. They have recently completed a series of three concept albums which focus on the theological aspects of God, Satan and man's relationship with the two. Some of their lyrical inspiration revolved around existentialist themes coming from the post-surrealist Georges Bataille, Friedrich Nietzsche and the German idealist Georg Wilhelm Friedrich Hegel.
