Sirenia is a Norwegian gothic metal band from Stavanger, Norway.
The band uses melodic instrumentals, synthesizers, and distorted guitars with female vocals, male death vocals, clean male vocals, a choir and violins. The lyrics are concerned with human existence, emotion, and mental states.
Due to musical disagreements and personal differences Morten Veland departed from Tristania in January 2001.
A few weeks went by when Veland had a new band along with three other members. He had written material for Tristania's next release but because of the split he used it towards Sirenia's debut album At Sixes and Sevens with other new material written for it as well. The band entered the studio by November or December 2001. The band failed to find a suitable singer prior to recording in France, so they hired a session female singer named Fabienne Gondamin.
