During the 1990s, Seigmen dominated the Norwegian rock scene and also made a name for themselves internationally, playing concerts abroad.

When Seigmen split in January 2000, Kim Ljung (bass guitar/backup vocals) and Erik Ljunggren (programming) went to Los Angeles and got an idea for a new band called Zeromancer.

Two more members of Seigmen joined them in Los Angeles: Alex Møklebust (vocals) and Noralf Ronthi (drums).

A little later, the band was complete, when they joined with Chris Schleyer (guitar), formerly of Kidneythieves and Prick which was released under Trent Reznor's label Nothing Records.

In 2001, Zeromancer released the album Eurotrash, which featured a cover version of the song "Send Me an Angel" by Australian band Real Life, the original having been a major hit in 1983.

Following the release, Chris Schleyer left the band and joined A Perfect Circle as a rehearsal guitarist.

During this time, Kim Ljung created his solo project, Ljungblut, and recorded a double-CD with Dan Heide.

Alex Møklebust did some producing for a few Norwegian bands (such as Gåte and Don Juan Dracula) and Erik Ljunggren has lent his programming skills to a number of other artists (Satyricon, Undergod) and began to study at a film school in Lillehammer.

A post on their official website, zeromancer.com, announced the release date for Sinners International as 13 February 2009, with a tour to follow in March.

After "The Death of Romance Tour" was done, Zeromancer almost immediately got back into the studio to work on their sixth album.

Zeromancer's music is largely industrial rock, similar to Celldweller, KMFDM, Die Krupps, Stabbing Westward, Oomph!, Orgy, Pitchshifter, and Rammstein.

Zeromancer derived their name by combining the titles of the novels Less than Zero by Bret Easton Ellis and Neuromancer by William Gibson.
