Great album. Really it’s a full length album and an EP on 1 disk. Must have for any Meshuggah fan. It is good even as an introduction to Meshuggah for fans of other types of metal. Newer albums like obZen may be too “harsh” or “extreme” for some. Like all Meshuggah tunes much of the CD is very “math metal” oriented but this disk is more likely to please the thrash/groove inclined metal heads. It also has some extremely jazz-infused moments. Highly recommended. I might have given it five stars but I reserve that for my most favorite items.
