Finnish band Höyry-kone (translation: Vapor Engine) started in 1991. The group was produced by Jussi Kärkkäinen (electric guitar) and Teemu Hänninen (drums). After going right through a number of personnel adjustments, they resolved on a lineup in 1995, which contains Kärkkäinen, Hänninen, Jarno Sarkula (bass), Tuomas Hänninen (electric guitar), Topi Lehtipuu (vocals), Jukka Hannukainen (vocals and secrets), Nina Lehos (oboe), and Marko Manninen (cello). Which was the lineup when their 1st recording, Hyönteisiä Voi Rakastaa, premiered. Two years later on in 1997, the group released Huono Parturi. The group added their interpretation from the Iron Maiden traditional “The Trooper” to some tribute album known as Slave to Power. The most recent incarnation of the group includes Kärkkäinen, Hänninen, Sarkula, Manninen, Erno Haukkala (trombone), and Matti Jalava (vocals and secrets).
