On its second full-length album, this hard-rocking quartet delivers 15 tracks of unrelenting aggression and focused intensity. Rather than overwhelm with huge sonic washes of guitar and booming drums, Tool employs a propulsive, snaky approach that makes use of undulating rhythms and clipped, percussive guitar riffs. Maynard James Keenan's vocals follow suit, opting for a heavily processed slow burn instead of the post-grunge bellow favored by so many hard-rock bands. Instead of flailing uncontrollably in all directions, the group's raw, energetic sound is tightly directed for maximum impact.

On songs like "Stinkfist," Keenan rails against injustice while the band churns mercilessly behind him. There is very little humor or light in Tool's worldview (except for song titles like "Hooker With A Penis"); these are songs of painstakingly articulated angst, and they are delivered in an earnest, deadpan manner. These fierce rockers are dead set on making their point, and make it they do, with all the bloodshed and carnage that entails.
