Humppa Folk Metal from Finland.
Vocalist Katla was forced to leave the band due to a tumor (not to be confused with cancer) that affected his vocal chords and could not be removed with surgery. This caused some live shows to be cancelled, and Pete Eskelinen filled until a replacement was found. Katla did, however, take part in recording of "Visor Om s**tet" in 2003.
Guitarist Somnium died by falling from a bridge on March 16th, 2003. His death was officially an accident, but Mika Luttinen (Impaled Nazarene) claims that he committed suicide. There are now no founders left in the band.
Keyboardist Trollhorn decided not to play live anymore since 2005 due to private reasons.
Tapio Wilska was fired in January 2006 and replaced in April by Vreth. Since then Katla has been writing Finntroll's lyrics again. Although they are from Finland, their lyrics are in Swedish as Katla is Fenno-Swedish (a minority in Finland whose primary language is Swedish).
