AMORPHIS的名字来源于”amorphous”即”未决定的形态”。AMORPHIS这支乐队由于对新的风格不断琢磨改进而闻名，从92年发行的Death Metal专集”The Karelian Isthmus”，到94年加入键盘融合traditional heavy metal,doom,death metaland ‘70s progressive rock风格的专集”Tales From The Thousand Lakes”，96年那张混合嗓音清澈见底，充满大量精彩键盘，迷幻般的吉他音色的”Elegy”，而此时乐队的成员也由最初的两人变成了六人，他们的歌词充满了诗意引人入盛， 99年AMORPHIS在沉默了一段时间又推出了”Tunela”，这张专集与”Elegy”又有大的区别，这张专集已经是倾向于旋律为主线的摇滚乐，你很难将他们与这之前的任何专集挂上钩，也因此导致了乐迷的大幅度更新.
Lead guitarist Esa Holopainen and drummer Jan Rechberger formed the band Amorphis in Finland in 1990. To complete their lineup they recruited vocalist/guitarist Tomi Koivusaari and bassist Olli-Pekka Laine. They released a demo in 1991 called Disment of Soul. The demo was so successful in getting attention for the group that they had acquired a record deal and released an EP the same year. They next released their first full-length album, The Karelian Isthmus, in 1992. The following year, their early demo recording session was released as Privilege of Evil. 1994 saw the group sending out their next CD, Tales From the Thousand Lakes. In 1994, Kim Rantala joined the band on keyboards, being integrated as a member of a band rather than the side musician he was replacing. An EP entitled Black Winter Day was released the next year. Their next album was Elegy. This disc showcased a new six-member lineup, completed by Pasi Koskinen as their second vocalist. The lineup at this point also included new drummer Pekka Kasari. In 1997 they released My Kantele. In 1998, Rantala left the group, being replaced by Santeri Kallio. The group released Tuonela with that lineup in 1999.
