After being blown away by "Show No Mercy", I knew I had to get more Slayer. Now, I haven't changed my mind, but I had higher hopes for this album. It is heavy and intense, but it is much less intricate than most of "Show No Mercy". The solos are kinda sloppy (what happened to those fast fingers from "The Final Command"?) and there are hardly any rhythm changes. The music in "Chemical Warfare" is almost exactly the same all the way through. But, it's still a cool song, very fast and hard. Dave Lombardo is one wicked drummer. Another thing is that the lyrics in the title track are Satanic, and really dumb. I'm not exactly religious, but it all just seems stupid. But, it's still a good song if you don't pay attention to what he's saying. "Captor of Sin" had a cool riff, I believe, but there's not much to say about it. "Aggressive Perfector" is pretty cool, aside from the fact that it almost sounds like a square dancing song (really, listen to the clip). I would recommend any of Slayer's 80's albums over this one, especially "Show No Mercy", but for the completist, go ahead and buy it. If you like fast, extreme metal, and you don't mind a little pseudo-blasphemy, "Haunting the Chapel" is a can't-miss. It ain't brilliant, but it ain't bad.
