For her work — often intense, poetic, dark and unpolished — Guðnadóttir draws on diverse sources, from contemporary composers such as György Ligeti and Kaija Saariaho to minimal music, ambient and noise. She is a multifaceted artist who has collaborated with musicians and composers such as Ryuichi Sakamoto (associate artist Holland Festival in 2021), Jóhann Jóhannsson, The Knife and Animal Collective.
