So many people have written great things about this album, what could I possibly add? Well, I heard H. once two summers ago, and finally bought the CD this year, because I never heard it after that, and that song was just haunting me. So when I bought it, I did nothing but listen to H. (song #3), for three days. I eventually graduated to the rest of the album, and bought the others (they rock too), and recommend Tool to anyone that likes music that quite simply kicks ass.
