Korpiklaani
Korpiklaani started as a folk music group named the Shamaani Duo. It was made by Järvelä and singer Maaren Aikio. When Aikio left, Järvelä renamed the group to Shaman. He started making folk metal instead of folk music. They made two albums, then the band's name changed again to Korpiklaani. They joined Napalm Records (a record label) and made more music.
