Takk... - Sigur Rós's fourth album and the one where they finally got happy, albeit in their own inimitable and deeply inscrutable, North Atlantic way. This is the record that gave the world 'Hoppípolla', a song which cemented Sigur Rós's reputation for being the go-to band for anyone wanting a sense of wonderful possibility in their film / TV show. The record also harboured moments of definitive Sigur Rós drama in singles Glósóli and Sæglópur, and high beauty in Sé Lest and Svo Hljótt.
