Kaija Koo: '90s

The ‘90s were without doubt Kaija Koo's decade, when albums such as Tuulten Viemää and Unihiekkamyrsky put her on the map as one of Finland's best-selling pop stars. Her sound is defined by breezy, beautiful tunes and big choruses, marked by bursts of fuzz-filtered guitar, which—when blended with Koo's warm, melodious vocals—imbue these hits with inherent charm.
