I'm no teenage fanatic that preaches "Tool's" greatness to everyone I meet, but these guys have got to be the envy of every other band in the genre. All of their albums are near perfect, and is simply some of the most powerful, smart, emotional, deep, and flawless music ever laid down. Only a few bands have amazed me as much: "Black Sabbath", "Pink Floyd", and "Soundgarden". I love each other album of theirs, but "Aenima" might be the best. My only complaint is that a third of the album are "interludes", non-songs that break it up, and are best heard only a few times. But the songs themselves are 5 star moving metal masterpieces.
