Norther formed under the name Requiem (Lindroos, Korpas, Hallio) in 1996 after various early stage band formations. The band's debut effort was the album, Dreams of Endless War, released through Spinefarm Records in 2002. The album entered the Finnish charts at position 17. At the time, Norther was playing shows only in and around the Helsinki area. That changed when the album Mirror of Madness came out in early 2003 (entering the Finnish charts at position 11). The group toured with Dimmu Borgir and Hypocrisy in late 2003. In early 2004, Norther released its third full-length album, Death Unlimited, which reached 17 on the Finnish charts.
Norther played several shows in 2005 and then recorded an EP, Solution7 (recorded at Astia Studio). It landed in the official Finnish charts at position five. Norther added Kristian Ranta's vocals afterward. In the summer of 2005, Norther used Studio Fredman in Gothenburg, Sweden, to record their fourth full length-album named Till Death Unites Us, with producers Fredrik Nordström & Patrick J. Sten. Soon after recording the album, Toni Hallio left the band to pursue other interests; Heikki Saari replaced him at drums. After its release in January 2006, Till Death Unites Us was number six on the Finnish album charts. Later the same year, the band composed the theme song ("Frozen Angel") for a major Finnish feature film, V2: Dead Angel produced by Solarfilms, Inc. The band is also featured in the film. In February 2007 Norther released a new EP, No Way Back, released only in Finland and Japan. The record hit number one in the Finnish charts. Later that year the released Amoral & Drone, and supported it with a European tour.
