2 LP Valtari is Sigur Rs sixth studio album which was initially released in 2012 on XL Recordings. Sigur Rs started recording Valtari, described by the band as an avalanche in slow motion in 2009 co-producing it themselves with Alex Somers in Reykjavik, Iceland. The title means roller in English with Jnsi saying it kind of fits with the album because its big and slow and rolls over you slowly."
