Silenoz (born Sven Atle Kopperud on 1 March 1977) is a Norwegian guitarist who is a founding member, along with Shagrath and Tjodalv, of the Norwegian symphonic black metal band Dimmu Borgir which he is the primary songwriter. He is also guitarist for the death metal supergroup, Insidious Disease.
Silenoz has been Dimmu Borgir's guitarist since they started. He also composes and writes lyrics for most of the band's songs. He contributes vocals (on "Stormblåst", its re-record, and "Godless Savage Garden") and bass (on "Stormblåst MMV"). He also sang lead vocals on their debut album "For All Tid". At first, he was known only as Erkekjetter Silenoz (Arch-Heretic Silenoz in Norwegian).
Another band Silenoz, or "Ed Damnator" as he was called, played rhythm guitar and occasional bass in was the Norwegian thrash metal band, "Nocturnal Breed". Before becoming a musician Silenoz used to work in a kindergarten.
Silenoz originally played bass, but he 'felt limited by only four strings'. He has played guitar since 1991, saying that he was inspired to play the guitar by Judas Priest, Randy Rhoads and Eddie Van Halen - in his words 'Real guitar players'.
For many years as guitarist in Dimmu Borgir, Silenoz appeared with long hair. However, as of 2012 he has appeared with a shaven head whilst maintaining a beard and various piercings.
Silenoz explained in an interview that his stage-name is derived from an alternative Latinised spelling of the Greek "Silenus," the name of a satyr-like being in Greek mythology who was a tutor to the wine god Dionysus, and was said to possess special knowledge and the power of prophecy while intoxicated. In the early days of the band, he used as stage name Erkekjetter Silenoz (erkekjetter being Norwegian for "arch heretic"), having it shortened later to Silenoz.
