22 Lunar Halo is music from throughout Sigur Rss career, twisted, bent, broken, and finally added to in the bands Reykjavk studio, to create a new perspective for a dance piece of the same title initiated and created by Taiwanese choreographer CHENG Tsung-Lung with musical director Kjartan Holm.

Originally released on Record Store Day, 22 Lunar Halo returns with new artwork, reversed in colour and printed in special ink.
