Amorphis

Amorphis is a Finnish progressive metal band founded by Jan Rechberger, Tomi Koivusaari, and Esa Holopainen in 1990. Initially, the band was a death metal act, but on later albums they evolved into playing other genres, including progressive metal, folk metal, and melodic death metal. They frequently use the Kalevala, the epic poem of Finland, as a source for their lyrics.
