Whenever looking upon Tool's catalogue, the same dilemma comes up on my mind: to choose which album I find better achieved between this one and Lateralus. From where I stand as a fan, both are fine pieces of music raised to some sort of perfection; but, until arriving at this level of feelings, things started on opposite points for each of them: if Lateralus had an immediate impact on me (I think because of my progressive roots, lets say it this way), Aenima needed much more time to digest and getting into; the outstanding opening track, "Stinkfist", was initially overshadowing everything else coming after - which, as a matter of fact, is precisely the main reason why I don't place Undertow at the same level of Aenima or Lateralus - the quality I find on the first 2 tracks is higher than on the rest of the album. But that's not the case here... out of the blue I started to contemplate the magnetism of the sound on the entire album, the epic "Pushit", or the power, speed and lyrics of the title-track, absolutely tremendous. With no doubt an album and band vital to know.
