I don't think their music would work at a festival atmosphere, especially during the day/evening. Their music is really sparse and hauntingly mellow and this type of vibe would only fit in a more intimate setting ( at least in the dark). There is a mood that is associated with their songs and to express it during this time of day with thumping bass coming from one of the tents can ruin the songs. The dynamics of the songs does it for me on the album but hearing them live I didn't feel those changes like I wanted to hear. Also, on some songs the vocals or instruments wouldn't exactly be on the same key.
