As a fan of hard rock since the mid 60's I was fortunate to acquire this CD from my dealer a couple of years back. Judging by the conflicting comments on the Amazon site Tool have stimulated a Love 'em / Hate 'em  response which is the hallmark of all important art. I must confess that it  was not until after a couple of listenings and the acquisition of the  lyrics via the Net that the true impact of this CD hit me. This is cutting  edge heavy metal and, in my opinion, the most significant creation from  that style of the 90's. The content is varied and interesting whilst  paradoxically managing to both intrigue and bludgeon the listener. Coupled  to a truly outstanding production Aenima delivers a aural experience of  shattering proportions which tested even my leviathan sound system to the  limit. Stuck away on the tip of Africa it is easy to miss a release of this  importance. I'm glad it did not pass me by.
