Amorphis

Initially, the band was a death metal act, but in later albums, they have evolved into a making songs that are more classifiable as mainstream but nevertheless with increasing complexity in their arrangements.

Amorphis is well known for their use of (the English translation of) the Finnish national epic, Kalevala, as a source for their lyrics.
