When Fear Factory were kinda new, they came out with "soul of a new machine", which I thought was aggressive and the vocals were very "deathy" and rough.
As they refined their sound, I caught back up with them with the album "obsolete", which in my opinion is their masterpiece. As the years have gone by, it seems to me
that they are always trying to recapture the magic concoction they created on "obsolete"....JUST MY OPINION. To be fair, I've only heard the first single off of the new album - "genexus".
