emphasis on Finnish humppa" and "the humor and irony they bring to the table." Finntroll's second album Jaktens tid was released in 2001 and became a chart success in their native Finland. Some of the songs on the album feature vocals performed by Jonne Järvelä of Korpiklaani, another band from Finland. While other folk metal bands began with metal before adding folk music, Korpiklaani started with folk music before turning metal. The roots of Korpiklaani can be traced back to a Sami folk music group under the name of Shamaani Duo, an "in house restaurant band" created in 1993. An album of folk music was released under this name before Jonne Järvelä relocated and formed a new band Shaman. The folk metal act Shaman was based on the folk music of Shamaani Duo. Two albums were released in 1999 and 2001 before Shaman changed their name to Korpiklaani. The change in name was accompanied by a change in the music. The traditional yoik vocals and the use of the Sámi language were dropped while the synthesizer was replaced with real folk instruments. Jonne Järvelä credits his work with Finntroll as the catalyst for the shift in emphasis from folk to metal. While Korpiklaani used an assortment of traditional instruments to deliver their folk metal, Finntroll relies on keyboards for Finnish folk melodies played in the humppa style. The keyboards in Finntroll are performed by Henri Sorvali who also performs in Moonsorrow, another folk metal band from Finland that he formed with his cousin Ville Sorvali in 1995. They released two demos, the first in 1997 and another in 1999, before the 2001 debut album Suden Uni. Moonsorrow blends folk metal with Viking metal by incorporating "Finland's traditional folk music forms into elaborate symphonic arrangements typical of Viking metal outfits such as Bathory and Enslaved." The adoption of folk elements was "becoming all the rage" in Finland by this point and other folk metal bands from Finland that began to emerge in the early 2000s included Cadacross, Ensiferum and later on Turisas and Wintersun. Ensiferum notably found themselves at the top of the Finnish charts with their 2007 single "One More Magic Potion". Finntroll, Korpiklaani, Moonsorrow and Turisas have all experienced chart success in their native Finland as well. There are also folk metal acts from the other Scandinavian countries. Icelandic group Skalmold is a notable example. The Norwegian act Glittertind
