Two listens in, and I'm really liking it. First song does start off slow, but it picks up after a bit and after that the album is just brutally fucking heavy. I'll agree that Meshuggah is a mood band, where I have to be in precisely the right mood to listen to it, but when that mood hits, I'm going to be bringing this one out a lot. Just crushingly heavy, some great riffs, awesome album.
