Finntroll is a finnish folk metal band that combines black metal with a Finnish form of polka called Humppa. Although they are from Finland, Finntroll's lyrics are in Swedish (the country's second official language), because Swedish sounds "damn trollish", according to the band's first vocalist, Katla (whose native language is Swedish). History Finntroll was founded in 1997, by Teemu "Somnium" Raimoranta (R.I.P. March 16th 2003), guitarist of Impaled Nazarene, and Jan "Katla" Jämsen. Their first demo, Rivfader, was recorded about a year later, in 1998.
