Amorphis is a Finnish metal band started by Jan Rechberger, Tomi Koivusaari and Esa Holopainen in 1990. Amorphis absorbed and incorporated influences from many metal genres, and with time passing their sound evolved dramatically. Initially, the band was a death metal act, but with time they have evolved into making music that is more classifiable as doom metal with folk influences, and, more recently, progressive metal and hard rock, utilizing increasingly complex arrangements and a less brutal sound.
