Wintersun is a metal band from Helsinki, Finland and was originally created by guitarist, keyboardist, bassist, songwriter and vocalist Jari Mäenpää as a side project to folk metal band Ensiferum, for whom he was lead singer and guitarist. In 2003, Mäenpää began pulling together songs that he had been working on since 1995. These songs followed specific themes described by Mäenpää as majestic, "spacy", and melodic. Wintersun is known for epic harmonies, fast tempos and both harsh and clean vocals. While Mäenpää planned to perform and record each instrument for the first album himself, he still required a drummer. He sent demos to Kai Hahto, former member of Rotten Sound, who agreed to perform the drums.
