Thats what this is. Out of the four Tool Albums released thus far, This one is the greatest. The Hardest. The Angriest. Most importantly the most experimental. All these other reviews are great but Ill just sum it down. Buy this album. Anyone can appreciate it. I mean. Im not just a rabid person who rates everything with five stars either. look at my other reviews. the only other one to get five stars is Snots "Get Some" so...dont take my lightly when I tell you to buy this album....now.
