HistorySusperia was started by Tjodalv (Dimmu Borgir, Old Man's Child) and Cyrus (Satyricon, Old Man's Child) in October 1998. After Tjodalv left Dimmu Borgir in the middle of March 1999 he started to concentrate fully on Susperia together with old-time friend Cyrus. At Wacken Open Air Festival in 1999, Tjodalv met with singer Athera (Vanaheim), who joined the band subsequently, followed by bass player Memnock (Old Man's Child, Vanaheim) and guitarist Elvorn. They recorded a demo, Illusions of Evil, in December 1999 at Pitfire Studio outside Oslo, which was mixed and mastered by L. Argedick. Synthesizer and piano parts were played by Mustis (Dimmu Borgir).The demo was sent out to different record companies and gained some positive feedback. They received a few offers from mainly major record labels, and signed in early 2000 with Nuclear Blast for four records. Susperia played their first live gig at John Dee in Oslo, following Ragnarok and Alsvartr; just a few months later they played at the Scream Magazine 10 year anniversary party.Susperia are not a Satanic band but through their lyrics they tend to criticize and question the views and morals of Christianity.On March 9, 2009, it was reported that vocalist Athera (real name Pål Mathisen) had suffered a heart attack. It was later confirmed that he had been rushed into hospital in Lørenskog, Norway, suffering from acute stomach pain and heavy bleeding. He was expected to remain hospitalised for some time. It was later announced that he would undergo a triple bypass operation on March 16, 2009.Cyrus is currently the touring bassist for Dimmu Borgir. Susperia joined Melodi Grand Prix in 2011, but lost before the semi final. They are currently recording an EP with Mustis (Ex-Dimmu borgir) joining them on keyboards. The EP will feature 2 new songs (most likely including the song "Nothing Remains") and 3 re-recordings with orchestral arrangements.Also Athera is currently the vocalist for Chrome Division under the name Shady Blue.
