Efterklang

Efterklang is a Danish word meaning reverberation, and it is also the name of a Danish experimental music group formed in Copenhagen in 2000. In acoustics, efterklang refers to the persistence of sound in a space after the original sound source has stopped. This reverberation is commonly described by a room’s reverberation time (RT60) and is influenced by factors such as room volume, surface absorption, diffusion, and layout. Reverberation colors how music and speech blend with their surroundings and can be manipulated in recording and performance to create sense of space.

The band Efterklang is known for blending elements of chamber pop, folk, and electronic textures with expansive orchestral arrangements. They have released multiple studio albums and EPs and have garnered international attention for their rich, atmospheric sound and attention to arrangement detail. Their projects often explore spatial dynamics and live performance, sometimes incorporating strings, brass, and electronics to build immersive textures. The group has collaborated with large ensembles on multi-artist and cross-genre projects and has contributed to the independent music scene beyond their own releases. They also founded the independent label Rumraket to release their work and that of other artists, reinforcing their commitment to collaborative and exploratory approaches to music.
