Efterklang is a Danish art pop, indie rock band from Copenhagen, formed in December 2000. Efterklang emerged in the front half of the 2000s with an enchanting blend of atmospheric pop and lushly arranged orchestral rock elements. The band 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. The band has recorded five studio albums and are currently signed to City Slang.

City Slang is an independent record label based in Berlin, Germany.
