Eternals Tears of Sorrow are a melodic death metal band from Finland.

Their music represents a wonderful transition between melody with beautiful piano and classical guitar and really heavy death metal.

The songs are epic, telling stories of fantasy and darkness.
They have 6 full albums:

Sinner's Serenade (1997)
Vilda Mannu (1998)
Chaotic Beauty (2000)
A Virgin and a Whore (2001)
Before the Bleeding Sun (2006)
Children of the Dark Waters (2009)

They have worked with other notable Finnish metal artists Sonata Arctica and Nightwish.

My personal favourite song is Sinister Rain from the album Before the Bleeding Sun;
Autumn harvest is here,
Time of greatest loss,
Take your final glance now
