Sigur Ros' fifth full-length LP (originally released in 2008) gets reissued by Piccadily Records this week, after having remained completely out of print worldwide for far too long. This 2xLP of post-modern ethereal folk is noted for being the band's first to be recorded, completed and toured all in the space of just one year - they had formerly toiled for years over their previous albums. It might also just be the best LP to highlight the band's 'realness'; the lyrics were originally meant to be in English, but they later returned to their own native Icelandic for a more authentic feel.
