The solo project of The Knife's Karin Dreijer, Fever Ray shares some of the band’s icy electronic atmosphere, but takes a slightly more organic-sounding approach. Fever Ray began after The Knife released Silent Shout. Xe worked on demos and song ideas by xerself, then collaborated with producer Christoffer Berg, who had mixed The Knife's music. Word of the project surfaced during the summer of 2008 and the first music, an instrumental version of "If I Had a Heart," appeared on Fever Ray's MySpace page that autumn. Fever Ray’s celebrated self-titled album was released in 2009. Dreijer returned to The Knife with 2013's Shaking the Habitual and the following year's Shaken-Up Versions. In 2017, xe issued the Fever Ray single "To the Moon and Back" shortly before the surprise release of the full-length Plunge in February 2018. Plunge was largely recorded in Karin Dreijer’s Stockholm studio in collaboration with the producers Paula Temple, Deena Abdelwahed, NÍDIA, Tami T, Peder Mannerfelt and Johannes Berglund. Fever Ray toured Plunge in 2018, xer first live shows in eight years. The show was recorded and later released as Live at Troxy in August 2019. In December of the same year Plunge Remix was released featuring remixes from Glasser, Tami T and Bunny Michael.
