Sigur Rós unveil instrumental versions of "Stormur" and "Ísjaki"

"Stormur" and "Ísjaki" have both been stripped of Jonsí's inimitable falsetto, leaving only the vastness of the post-rock instrumentation to shine.

Kveikur is out now. Sigur Rós’ Georg Holm and Orri Páll Dýrason have collaborated on a new soundtrack called Circe, which will back BBC circus/performing arts documentary The Show Of Shows.

Stream six of the Kveikur instrumentals, including the pair of newly shared ones, below.
