Iceland pop experimentalists Múm met while working on a children’s play. Formed by Gunnar Örn Tynes, Örvar Smárason, and classically trained twin sisters Gyda and Kristín Anna Valtysdóttir in 1997, they soon became electronic key-figures. múm have released on Morr Music & Fat Cat Records & are one of Iceland’s most important pop outfits. The band’s lineup is in a state of constant change. So is their music.
