This album, while not as sophisticated (song wise) as AENIMA and UNDERTOW has some amazing songs on it. Don't buy this expecting an AENIMA or UNDERTOW or even LATERALUS like album, this is early TooL, though still in the stages of developement and not mature yet, still extremely powerful. This along with Aline in Chains's Sap is the best EP ever recorded. It rocks from start to finish. While not as long as later TooL, it leaves you at the edge of your seat. My favorite songs off it are Opiate and Hush. Already on this album TooL was questionning religion and obviously angry. When you'll hear Maynard chanting :"Jesus Christ, why don't you come save my life now. Open my eyes, blind me with your light now..." you'll be mezmorized. The lives tracks are especially well recorded (Jerk Off and Cold & Ugly). Opiate has it's own sort of dark side, it contains some of the most dreary music ever, which is perfect since it fits like a glove the themes of the album contains. You can't go wrong with TooL, each and every cd or unreleased track is worth owning. This is probably they're most agrrrrressssive album of all often compared to Korn's first. While this was simply a collection of TooL's heaviest songs at the time it's still worth buying but you'll probably enjoy this more if your already a TooL, a good place to start, though not the best.
