Shiver is the second studio album by Icelandic musician Jónsi, frontman of the post-rock band Sigur Rós.

Cook shared remixes of Sigur Rós tracks, as well as demos for Jónsi,[12] hinting at further collaboration between the two in the future.

On 28 June 2019, Jónsi was interviewed by The Feed SBS, where he shared he had an upcoming collaboration with Swedish singer Robyn for his next album, stating, "It's really good.

Jónsi had made a career on sweeping music that plumbed the depths of the human experience and our connection to the natural world.

Cook’s production exists at the opposite end of the spectrum: synthetic, sometimes abrasive, and often on the cutting edge of experimentalism.

[25] Jónsi confirmed the release of the final single for the album, "Salt Licorice" featuring Swedish singer Robyn, on 29 September.
