Juhani Juice Leskinen, better known as Juice Leskinen was one of the most important and successful Finnish singer-songwriters of the late 20th century. From the early 1970s onward he released nearly 30 full-length albums and wrote song lyrics for dozens of other Finnish artists. Several of Leskinen's songs have reached classic status in Finnish popular music, e.g., "Viidestoista yö", "Kaksoiselämää" and "Syksyn sävel". His early records are considered staples of the so-called Manserock movement of the mid-'70s. He also wrote poetry and plays and published nine collections of verse and seven plays.
After moving to Tampere to study English translation in 1970, Leskinen began his recording career in 1973 with the eponymous debut album of Juice Leskinen & Coitus Int. One more record, Per Vers, runoilija, was made under the same band name, but from then on he released records with several line-ups, most notably Juice Leskinen Slam and Juice Leskinen Grand Slam from the late 1970s until the mid-1980s.
