Claude says:Sigur Rós's 1999 debut is glacial post-rock that builds from whisper to cathedral without ever breaking stride, and you keep returning to Svefn-g-englar—that ten-minute drift where Jónsi's Hopelandic vocals float over bowed guitar like they're the only sound left in Iceland. Over six years you've let it sit with you in small doses, the kind of album that asks for solitude more than repeat spins but never wears out its welcome.
