Efterklang is a band from Copenhagen, Denmark, consisting of four core members (Mads Brauer, Casper Clausen, Thomas Husmer & Rasmus Stolberg) who have played together since 2001. They are often joined by musicians like Peter Broderick, Frederik Teige, Heather Broderick and Niklas Antonson when they perform live and they also have a 5th member (Rune Mølgaard) who has been a part of Efterklang since the beginning, but who has taken a more secluded role in the past years.
The Springer EP was originally released in a limited edition of 500 handmade covers in white fake fur. While printing the numbered Under Giant Trees EP Efterklang decided to store the first twenty copies as a collectors object. Unfortunately these were stolen. As a countermove 29 copies was stamped with a letter which were sold by auction at EBay and the profit was given to the enviromental organization Nepenthes to protect the rain forest.
