opening theme song for the Canadian-Irish historical drama television series Vikings. In September 2009, Dreijer composed the soundtrack to Dirty Diaries, a collection of feminist pornographic short films. In a review of the collection, Swedish newspaper Smålandsposten described the soundtrack as appropriate for the film, though repetitive. Dreijer performed as Fever Ray at the 2010 Coachella Festival and received positive reviews. In September of the same year, they performed at Electric Picnic in Ireland. Contrary to a statement from the film's director, Dreijer did not make a cameo appearance in the 2011 film Red Riding Hood. However, the soundtrack features a new track performed by Dreijer as Fever Ray, "The Wolf", as well as "Keep the Streets Empty for Me" from their debut album. "The Wolf" was also featured in Ubisoft's Far Cry Primal announcement trailer, as well as during the game's final mission. Dreijer wrote the music for the theatrical adaptation of Ingmar Bergman's 1968 horror film Hour of the Wolf, which premiered at Stockholm's Royal Dramatic Theatre on 12 March 2011. One of these tracks, "No Face", appeared in demo form on the 2012 compilation album We Are the Works in Progress, organised by Blonde Redhead to benefit victims of the 2011 Japanese tsunami. In February 2016, Dreijer announced they had written and produced music for a theater play called Vahák (English: Violence), which plays on themes of colonial and homophobic violence. That same month, Dreijer revealed in an interview with The Fader that they were working on solo music, though they were unsure whether it will be under the Fever Ray moniker. On 20 October 2017, Dreijer released the single "To the Moon and Back" and its accompanying music video. It served as the lead single to their second studio album, Plunge, which was released on 27 October without prior announcement. The album received widespread acclaim from music critics upon release and appeared on numerous year-end lists. In support of the album, Dreijer embarked on an international tour throughout 2018, with the first leg of which was held in Europe and began in February, followed by a North American leg held in May. More European dates were later added from June until November. In the 2018 Swedish Grammys, Dreijer and the producers they collaborated with on Plunge won the award for "Producer of the Year". Plunge was also nominated for Best European Independent Album at the IMPALA
