Sigur Rós members Georg Hólm and Orri Páll Dýrason, along with their buddies Hilmar Örn Hilmarsson and Kjartan Holm, have been working on the soundtrack for a new BBC documentary called, The Show Of Shows; a compilation of archived footage of circuses, carnivals and vaudeville acts spanning 100 years.
