"Mold" is the first release from Jónsi since he released his Shiver solo album in October last year, which marked his first solo album since 2010's Go.

The new track is produced by PC Music boss A. G. Cook and Jónsi, and is accompanied by a video montage created and edited by Damian Hale, with video parts directed by Ingibjörg Birgisdóttir, Máni Sigfusson, Jun Tamukai, Nina Mcneely and Adam Powell.

Jónsi's recent solo album also featured production from A. G. Cook, and collaborations with Robyn and Cocteau Twins' Elizabeth Fraser.

Last month Sigur Rós released their Odin’s Raven Magic album.

Jónsi's "Mold" single is out now.
