biografía : Deathspell Omega
Initially, Deathspell Omega produced raw, traditional black metal akin to Darkthrone's Transilvanian Hunger. However, their 2004 release, Si Monumentum Requires, Circumspice, marked a change to a vastly more technical, experimental, and well-recorded sound featuring such musical influences as Russian Orthodox chanting and choral music.
The band's work after Si Monumentum Requires, Circumspice has been even more experimental and technical, with the 5 tracks they released in 2005 - on Kénôse and a pair of splits - totaling nearly eighty minutes in length and actually exceeding the length of Si Monumentum Requires. The second volume of the band's trilogy, Fas - Ite, Maledicti, in Ignem Aeternum, was released on July 16, 2007, outside the United States, and the following day within the United States, to considerable acclaim. The band released another EP in January 2009, entitled Veritas Diaboli Manet in Aeternum - Chaining the Katechon. The final album in the trilogy, Paracletus, was released by Norma Evangelium Diaboli and Season of Mist on 9 November 2010.
Very little is known about the members of Deathspell Omega, as the band does not have an official website or release information about their membership; at various times, members have been reported to include Mikko Aspa, Shaxul, Hasjarl and Khaos. They have given interviews over the years that explain more about their beliefs and ideology.
