Early career and Melodifestivalen

Nanne's early public profile grew in the 1980s with the group Sound of Music. The trio competed in Sweden's national selection, Melodifestivalen, more than once and placed strongly.

She was a founding member of the group One More Time, which won the Swedish selection on one occasion and went on to represent the country at the Eurovision Song Contest, finishing among the top placings in the international final. The group enjoyed broader European attention in the 1990s through album releases and radio play.
