For their third release, Tool explore the progressive rock territory previously forged by such bands as King Crimson. However, Tool are conceptually innovative with every minute detail of their art, which sets them apart from most bands. Make no mistake, this isn't your father's rock record. Sonically, the band has never sounded tighter. Long exploratory passages are unleashed with amazing precision, detail, and clarity, which only complements the aggressive, abrasive shorter pieces on the album. There is no compromise from any member of the band, with each of them discovering the dynamics of his respective instrument and pushing the physical capabilities to the limit. Topics such as the philosophies of Bill Hicks (eloquently eulogized in the packaging), evolution and genetics, and false martyrdom will fly over the heads of casual listeners. But those listening closely will discover a special treat: a catalyst encouraging them to discover a world around them to which they otherwise might have been blind. If these aren't good enough reasons to listen to Ænima, then just trust the simple fact that Tool deliver the hard rock goods every time the band chooses to release something. ~ Rob Theakston

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.
