The band soon earned the label of a black metal supergroup, consisting of Kristoffer "Garm" Rygg on vocals, Carl August Tidemann on guitar, Skoll on bass, and the two other original members, Hellhammer on drums and Steinar Sverd Johnsen as the main composer/keyboard player.

He was succeeded by Simen "ICS Vortex" Hestnæs, who had previously provided vocals on three Arcturus tracks: "Master of Disguise," "The Chaos Path," and "Painting My Horror" on La Masquerade Infernale.

The statement concluded with a tribute to the band's fans: "We are humble and grateful to all the people that have supported and loved us over the years.

Furthermore, ICS Vortex mentioned plans to resurrect "a band or three" in a blog post shortly after his removal from Dimmu Borgir.

Arcturus finally performed their reunion show on 9 September 2011 at the KICK Nattklubb & Scene in Kristiansand, Norway.

On 10 October 2014, Arcturus confirmed on Facebook that ICS Vortex had finished recording vocals for their as-yet-untitled album.

Unparalleled in creativity, musicianship and artistic approach since their foundation days, mastermind Steinar 'Sverd' Johnsen and his cosmic crew, consisting of past and present members of bands like Ulver, Mayhem, Dimmu Borgir, Borknagar, and Ved Buens Ende, have been dancing their very own tightrope between genius and madness ever since.
