Having attended a one-off screening at the Manchester Cornerhouse, I can safely say that this film is visually and sonically stunning. The documentary chronicles Sigur Ros' 2006 free tour of Iceland, with every song introducing you to a different corner and aspect of Iceland. Each filmed performance takes place in a different location, from abandoned villages to massive open air concerts. And what performances they are!
Interceded throughout are interviews with the band, their support string section - Amiina and in one memorable instance, a man who constructs musical instruments from rocks. They all come across as a thoroughly likable group who have a deep love for their home-country. This film serves as both a wonderful introduction to Sigur Ros and their music as well as a great advert for Iceland.
