Kari was one of the founder members of the progressive doom metal band The 3rd and the Mortal. The band was a source of inspiration for many other bands worldwide, among them Nightwish and The Gathering. After leaving The 3rd and the Mortal in 1995 she has released five studio albums; Spindelsinn (1997), Mesmerized (1998), Pilot (2001), Other people's stories (2004) and Time to Tell (2014). In 2014 and 2015 she has toured Europe and Latin America with The Sirens - a project she has together with Anneke van Giersbergen (ex The Gathering) and Liv Kristine (ex Theatre of Tragedy).
Kari Rueslåtten's forthcoming studio album, "To The North", is inspired by the dramatic landscapes of northern latitudes. "To the North" is a follow up to last year's successful "Time to Tell" album, and this time Kari Rueslåtten has brought a darker-edged atmosphere to her acoustic, melancholic Norwegian folk. She has taken inspiration from Norwegian and Celtic folk music, along with artists such as Loreena McKennitt, Tom Waits and Emmylou Harris.
