This album is amazing. Period. Fear Factory deliver a vicious metal assault sure to please even the most discriminating of headbangers. Their futuristic thrash sound was led by Burton C. Bell's fearsome growl, Dino Cazares's interesting and spine-crushing riffs, and the thumping rhythms of bassist Christian Olde Wolbers and Drummer Raymond Herrera. Perhaps better than any other album, "Demanufacture" combines the accessibility of thrash with the all-out heaviness of death metal.
But there's more. A lot more. Burton could sing, and he did so quite often here. He had a very cool, haunting singing voice that provided a nice contrast with the aggression that characterizes much of the album. On the title track, he sings the first few lines, making it that much more effective when he turns on the growl. "Dog Day Sunrise," a cover of a song by a band called Head of David, features entirely clean vocals, and it's downright mesmerizing. What's more, the band also added an industrial element that helped to differentiate them from other metal bands, especially at the time. Although the industrial samples are used conservatively, they add an extra dimension to the already heavy songs.
If one song here deserves special mention, it's the closer "A Therapy for Pain." It's a slow, melodic, nine-plus-minute epic with an indescribably eerie sound. Burton's foreboding, almost angelic vocals combine with heavy doses of industrial samples to make a song that's truly chilling. For some reason, it strongly reminds of the Lone Biker of the Apocalypse's theme music from the movie "Raising Arizona." But anyway, it's a great song, and a brilliant way to end an album. In conclusion: this album is a masterpiece. If you don't have it, you should. End of story.
