Has some good ideas, but overall the band seems like they are in a rush. They have yet to learn how to build atmosphere effectively through repetition and transitions. However, they get it more or less right on their next album, Noir.
Callisto are a superb band with peak musicianship, and this should be noted as such. However, they really aren't doing anything new within the genre of post-rock or post-metal. Guttural vocals, crushing guitar, emotive soundscapes, as well as some truly beautiful passages, such as "Storm" are to behold. It might not be ground-breaking or timeless, but it's never to be scoffed at.
