This is Tool's greatest CD (which is saying somthing). I love this CD it is the greatest modern day heavey metal CD. The jewel case is made so when you put the pictures inside under the case the pictures move. Which is a nice feature, you can even see what Arizona bay would look like. All the tracks are meaningful, like Stinkfist, and some funny, like Intermission. Aenima is amazing and I think their best song (which has some Bill Hicks references). Third Eye is a great tribute to the late Bill Hicks. To fully understand this CD you should also add Bill Hicks's CD "Arizona Bay". Warning: If you chose to take my advice also be aware that you may find some of Bill Hicks's humor to be offenceve. Any way back to this CD, this is a must have for any Heavy Metal fan.
