Finntroll came together for the first time in 1998. The band featured numerous artists members of Moonsorrow, Barathrum, and Impaled Nazarene. The band members of Finntroll are guitarsist Somnium (Impaled Nazarene, Thy Serpent), Katla the vocalist, drummer B. Dominator (Barathrum, Rapture), Örmy on live guitars, Trollhorn (Moonsorrow) on keyboards and Tundra on bass. The band first made their demo tape, "Rivfader" in 1998, followed by their first full length CD, "Midnattens Widunder" in 1999. Despite being a Finnish band, Finntroll chooses to write their lyrics in Swedish being quite rough sounding. In 2001 they release Jaktens Tid their second full length CD. In 2003 they release a new CD with a new sound. Intended as experimental version before their next work, the band decided to record it anyway.
Unfortunately, after the recording of the forementioned album, Finntroll was struck by the tragic death of the guitarist Teemu "Somnium" Raimoranta in March 2003. This didn't stop the band however. In 2004 they released the EP "Trollhammaren" and the album "Nattfödd".
