This EP was originally composed to accompany a dance piece by Merce Cunningham (a long-time collaborator of legendary avant-garde composer John Cage). Cage was of course known for his use of chance as a compositional technique, and he also embraced non-musical sounds as acceptable instruments, along with the help of electronics. No surprise, then, that this EP is much more abstract and unstructured than Sigur Rós's past material. It's an album about fragments of spoken words, music boxes, piano loops, footsteps and unidentifiable noises. Interesting, but a bit dense and completely hook-free.
