This album is a wet dream for every heavy music fan with a brain. Beautifully layered guitars, a throbbing heart-beat bass line and rock solid drumming, teamed with Maynard's thought provoking and poetic lyrics, make for a near perfect sonic assault that will make you think. Go out and buy all of Tool's albums. WARNING if you have attention deficit disorder, or have trouble understanding any more complex themes than "breaking stuff" or "Daddy didn't love me" you may be better off listening to Limp Bizkit or Korn.
