Enslaved released their 13th full-length studio album, In Times, on 10 March 2015 through Nuclear Blast. The album received positive reviews from music critics, with AllMusic's Thom Jurek noting that the band are "still pushing at the boundaries of the music that inspired them back in 1991 when guitarist Ivar Bjørnson and vocalist/bassist Grutle Kjellson (13 and 17 years old at the time) first formed the band."
