If you can call Metallica "heavy metal", then you might as well say that Eminem is a nice guy. Tool's more heavy than Metallica ever was or will be. Some of the songs on this disc are about as heavy as heavy metal gets. It's dark, disturbing, and is guaranteed to make you shiver. If you don't, it's obvious that you're a robot. Songs like Stinkfist, Eulogy, the title track, and 46&2 are some of Tool's best yet. While songs like Third Eye and Pushit are a definate test of your patience, they're also really good. If you can make it through the end of Third Eye, then you're a true Tool fan. Eulogy and Useful Idiot are pretty self-explanatory. There's also an Intermission track (if you've seen Monty Python & The Holy Grail, there's an intermission scene and they play cheesy music that's kind of like this), that's how long the CD is. It's the longest CD in my collection, clocking in at 77 minutes . 46&2 was one of the songs that got me interested in Tool in the first place. Undertow was obviously aimed at a more mainstream audience, but Aenima was obviously aimed at a more hardcore audience (there's no censored version). If you liked Perfect Circle's Mer De Noms, and think that Tool is anything like them, are you dead wrong. If you like heavy metal, this is an album you must check out. Can't wait for Tool's next album.
