Claude says:Sigur Rós arrived in 1999 with Agaetis Byrjun as Iceland's answer to a question nobody asked—glacial, orchestral post-rock sung in Hopelandic (a made-up language) that somehow made sense on first listen. You've returned to it sparingly but steadily since 2007, letting Svefn-g-englar do most of the heavy lifting, which tracks given how that track alone carries the weight of the album's entire emotional arc.
