Kerkko Koskinen (born January 7, 1973, in Espoo, Finland) is a reluctant star of Finnish popular music. He was the bandleader, songwriter, pianist and key founding member of the popular band, Ultra Bra, before embarking on his solo career.
Ultra Bra was formed in 1994 in order to perform in a song contest sponsored by the Democratic Youth Union of Finland. Initially considered a lark by student-intellectuals, the band decided to continue making music after winning the competition. Their first EP, Houkutusten kiihottava maku ("The Exciting Flavor of Temptations"), was released in 1995 and, soon after, the band was signed by the major Johanna label. Their first album, Vapaaherran elämää ("Life of a Free Lord"), was released in 1996 and was selected the album of the year by at least one influential music magazine. Koskinen composed all the songs and performed on keyboards. Their second album sold in triple-platinum figures, and the third and fourth followed suit.
