Label: Krunk After taking a long break from recording new material, Sigur Rós' sixth album, Valtari, is a welcome return for the Icelandic soundscape pioneers. Their previous album Med Sud I Eyrum Vid Spilum Endalaust had been their most intimate and cheerful record to date with songs that could actually be called "songs" and the band stripping their sound down to the point where you could almost pick out individual instruments in the mix. Valtari is a return to the epically somber and sonically all-encompassing approach the band perfected on their first few albums. Filled with giant washes of sound bathed in reverb, echoing keyboards, smears of strings, and massed backing vocals, the album ebbs and flows from giant crescendos to heartbreakingly intimate moments with Jonsi's otherworldly voice riding the waves like a mythical dolphin. Each song creates its own insular world of atmosphere and emotion that can be so intense that when they end, the silence makes it feel like you've been yanked harshly out of a reverie.
