Deathspell Omega is a French black metal band formed in 1998. 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. From 2004 to 2010, they released 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 has come from the post-surrealist Georges Bataille as well as existentialist themes.
