The co-founder left the band in 2009, and Fear Factory went on to release Mechanize the following year with Gene Hoglan behind the kit. Then they opted to use computer percussion on their next title.

Herrera tells Metal Wani: "I thought Mechanize was really good - Gene did a great job. It was probably a little too thrashy for me, but for the most part it sounded like they were trying to recapture the Demanufacture feeling. They did a pretty good job doing that."
