Kim Larsen was born in Copenhagen. Inspired by The Beatles and rock and roll, he began as a songwriter and guitarist. In 1969 he met Franz Beckerlee and Wili Jønsson, and the three founded Gasolin' which, later joined by drummer Søren Berlev, became one of the most successful Danish rock bands. The band dissolved in the late 1970s.
In 1979, Larsen participated in the Danish stage of the Eurovision Song Contest with the song "Ud i det blå" (lit.: Out into the blue). He came third out of 17 participants. The song was included on this album 231045-0637.
Around 1980, Larsen moved to New York. He released two albums but was not successful in breaking through in America and returned to Denmark after a few years.
Kim Larsen released a number of solo albums in the 1980s, topping the charts in 1983 with the album Midt om natten (en: In the Middle of the Night). The album more or less became a soundtrack for the movie by the same name based upon it.
In 1983, Larsen founded the band Kim Larsen & Bellami and released four albums until 1992, when after a couple of different line-ups, the band broke up. He then released another solo album, Hvem kan sige nej til en engel (Who Can Say No to an Angel). In the mid-1990s he founded the band Kim Larsen & Kjukken which was based in Odense.
He wrote a tribute song about MS Jutlandia's contributions as a hospital ship of Danish Red Cross during the Korean War. The song titled "Jutlandia" became a large hit in Denmark in 1986.
