I have no info on this outside of what’s included in the teaser description:
Three months ago in August 2010, French filmmaker Vincent Moon and Efterklang’s 8 piece-live band met up on an island in the Danish country side. The objective was to shoot a film. A film with the same length as an album, and a film full of performances, experiments and collaborations.
Over an intense period of 4 days Efterklang collaborated with more than 200 local musicians, kids and parents, creating new performances and interpretations of songs from their Magic Chairs album. It was all filmed by Vincent Moon who same time conducted several filmic and musical experiments with Efterklang as his dedicated play mates.
