Leaves' Eyes is a symphonic metal band from Germany and Norway. They were formed in 2003 by Liv Kristine, formerly the lead singer of Theatre of Tragedy, and the entire line-up of Atrocity. To date, the band has released eight studio albums, a single, six EPs, one live album and a DVD. Most of Leaves' Eyes' lyrics, written by Liv Kristine until her departure in 2016, concern Norse mythology and the Viking Age. The melodic singing vocals of Liv Kristine and her replacement Elina Siirala are occasionally backed up by death growled vocals from Krull, identified under the vocal style Kristine refers to as "beauty and the beast".
