The experimental Danish post-rock group Efterklang emerged in the front half of the 2000s with an enchanting blend of atmospheric pop and lushly arranged orchestral rock elements. They found an audience, especially in Europe, after releasing their first two albums on England's the Leaf Label; the attention led to a deal with 4AD. 2012's expansive Piramida, recorded at an abandoned Russian coal-mining settlement on a remote Norwegian island, was a creative career high point, motivating future experiments like the 2015 opera Leaves: The Colour of Falling. During a band hiatus, Efterklang's core members formed another group called Liima, who issued a pair of albums in 2016 and 2017 before returning to their primary project for 2019's Altid Sammen and 2021's Windflowers.
