With Lamented Souls he released a 1995 self released demo, at 2003 the “Essence of Wounds” EP and at 2004 the “The Origins of Misery” full length album. A new full length release with the tentative title “Echelons of Decay” has been announced.
The year 1997 I.C.S.Vortex made a guest appearance on the Arcturus album “La Masquerade Infernale”. He sang on three songs, “Master of Disguise”, “The Chaos Path” (in which he handled all lead vocals, wrote the lyrics, and co-composed this song), and “Painting My Horror”.
In 1997 he also became the vocalist of the folk/progressive/black metal band Borknagar. He handled the vocals on “The Archaic Course” album, wrote half of the lyrics and composed the song “Ad Noctum”. On Borknagar`s fourth full-length album”Quintessence” Vortex added bass to his vocals duties. The song “Colossus” was written by Vortex and guitars was also preformed by him on this track. The song “My Domain” on Borknagar’s “Universal” album (2010) features Vortex on vocal. The collaboration plowed way for a new formation to grew forth.
