Personal information

Born on: 30.08.1977

Cornelius Jakhelln (born 30 August 1977 in Kristiansand), also known as Cornelius von Jackhelln, is a Norwegian vocalist, musician, writer and poet.

Born in Oslo but currently residing in Berlin, Cornelius was 18 years old when he and Lars "Lazare" Nedland formed the avant-garde metal band, Solefald. Along with being a lead vocalist, guitarist, bassist and composer in the band, he also handles the vast majority of lyric writing for the band. Solefald has since released one demo, and five full-length albums, with a sixth due in late 2006. In December 2005, the band was nominated for the Norwegian Alarm award for best metal album for the album, Red For Fire: An Icelandic Odyssey Part 1.

Cornelius' first time recording with a band other than Solefald was in July 1999, when Cornelius performed guest vocals for the gothic metal band Monumentum for the songs "Black And Violet", a cover of the Italian band Death SS, and "The Colour of Compassion". These recordings were released in 2004 on the Monumentum compilation album, Metastasi.

In 2003, Jakhelln began working on a new band. The name chosen was Sturmgeist, and the band plays an experimental style of black/thrash metal with lyrics sung in English, Norwegian, and German about Germanic mythology, war, and recitations of Goethe poetry. On January 24, 2005, Sturmgeist released their first full-length, entitled Meister Mephisto on the record label, Season Of Mist. Since then, Sturmgeist has gone on a small European tour, and has recruited two more official members, John "Panzer" Jacobsen on guitar, and Christian "Anti Christian" Svendsen on drums, ending the band's time as a solo project. Sturmgeist's second full-length, entitled Über, was released October 16, 2006 through Season of Mist.

On August 26, 2005, Cornelius also announced on his official website that he would finally be recording an electronica album in Sofia, Bulgaria that he had been planning for six years. He has described the project as a combination of electronica, darkwave, hip hop, drum'n'bass and black metal.
The album is out now in 2007, the name of the band is G.U.T meaning Grace Under Torture and the name of the album is My only drug is madness.
