Krüger's first TV appearance was at the age of 11, in a youth show called "Halvsju". She got her breakthrough in 1988, first by winning the Norwegian Melodi Grand Prix with the song "For vår jord" ("For Our Earth"), still a student at Langhaugen Skole (1986–89). This qualified her for the Eurovision Song Contest 1988 final, held that year in the Irish capital Dublin, where she finished fifth. Later that same year she released her debut CD, "Fasetter". She sings the ballad "You Call It Love", from the film "L'etudiante", a song composed by Vladimir Cosma. The song was covered by Richard Sanderson.
