The band's epic music has not come without a number of lineup changes, one of the most notable was the departure of ICS Vortex on bass and clean vocals and Mustis on keyboards in 2009. The band went on to record their next album with the Norwegian Radio Orchestra and the Schola Cantorum choir totaling more than 100 musicians and singers.
Here is Dimmu Borgir (still with ICS Vortex) playing Progenies Of The Great Apocalypse live at Wacken
