Silenoz (real name Sven Atle Kopperud, born in March 1 1977), is a Norwegian guitarist who is a founding member, along with Shagrath and Tjodalv, of the Norwegian symphonic black metal band Dimmu Borgir. He is also guitarist for the death metal supergroup, Insidious Disease.

Biography
Silenoz has been behind the guitars since the band started. He composes most of the riffs and melodies that are a large part of the band's sound. He is also Dimmu Borgir's predominant lyricist, also contributing backing vocals which can be heard on "For All Tid", "Stormblåst", its re-record and "Godless Savage Garden" as well as his bass contribution on "Stormblåst MMV". In the early days of the band, he used as stage name Erkekjetter Silenoz which means arch heretic, having it shortened later to Silenoz.

Another band Silenoz, or "Ed Damnator" as he was called, played rhythm guitar in was the Norwegian thrash metal band, "Nocturnal Breed". Before becoming a musician Silenoz used to work in a kindergarten.

Silenoz has written majority of Dimmu Borgir's lyrics and also based the songs in the album In Sorte Diaboli on a narative of his composition which he has explained to be the basis on the next two upcoming albums. Part of the narrative is available in the special edition of In Sorte Diaboli.

Silenoz was featured as a voice actor in the Adult Swim cartoon Metalocalypse. This episode kicked off the second season of the popular show and debuted on Adult Swim Fix on Friday, September 21, 2007.
