This album really has the feel of a band that has really grown together, evolved and have a real sense of understanding with each other.
Whilst this album perhaps doesn't reach the technical levels of some of their previous works (In Death Is Death, Bleed etc.) I do feel like they have excelled in their creative areas, producing an album that flows much better than their previous works with no over-indulgence and with a feeling of less disparity than can be heard in their EPs for example. But Meshuggah have now achieved though, is a real sense of coming-togetherness. It is almost as though they have purposefully toned down their technical efforts in order to gain more of a sense of a single unit producing intelligently crafted grooves, something that has really given this album a sense of maturity.
There is more of a feeling of groove on this album. On the whole, the album is chuggier and less chaotic than some of their previous releases. The title track I am Colossus introduces slow, heavy and deep guitars, Do Not Look Down has the guitar and drums playing an excellent inter-twining groove, Break those Bones, Behind the Sun, Demiurge are similar in that respect. The Hurt That Finds You is an absolute all-out assault with a wonderfully atmospheric closing out whilst The Demon Is Surveillance has fast paced double bass drums through-out with complex 4/4 timed riffing for the majority of the song.
There is a real mix here and whilst the album may take a few listens to fully appreciate, especially for those that like their music layered and complex.
