Empyrium started as German symphonic folk doom metal band founded in 1994 by Markus Stock (mostly using the pseudonym Ulf T. Schwadorf) and Andreas Bach, but later many other participated. Their first two albums, A Wintersunset and Songs of Moors and Misty Fields, can be considered as doom metal with folk and symphonic influences. They combine harsh and operatic male vocals, with deep slow guitar parts, atmospheric keys. Their music is heavy, dark and romantic.
The following two albums; Where at Night the Wood Grouse Plays and Weiland are acoustic, move to the genre of neofolk. Instead of keyboards, the band switched to acoustic instruments such as violins, cellos and the flute. Operatic male vocals are still used, and in Weiland the band uses choir with occasional Black Metal rasps. Though the music still remains dark and melancholic, Empyrium's music has mostly moved away from Heavy Metal. Their last album -- Weiland is real masterpiece in the neofolk genre.
