This album is for Tool pretty much the same thing that 'adrenaline' was for the Deftones. This album is a pre-mature display of raw fury. There are hardly any progressive hooks or colorful contrasts in this recording, but that is not what this album is about. This album is about being pissed off, and is a must have for any die-hard tool fan. More casual fans of Aenima, Lateralus, or 10,000 Days may not enjoy, but to fans of Undertow, this album is well worth every last dollar.
