Thought Industry (formerly named "Desacrator") is an American progressive metal band It was founded in Kalamazoo, Michigan in 1989 by vocalist/bassist Brent Oberlin, drummer Dustin Donaldson (who formed I Am Spoonbender in 1997), guitarist Christopher Lee Simmonds (aka Christopher Lee), and guitarist Steve Spaeth who replaced original Desacrator guitarist, Dan Roe. Spaeth left the band due to internal conflicts with Simmonds and started the band Clockmaker.

The position was filled by guitarist Paul Enzio in time for 1992′s "Songs For Insects", their Metal Blade Records debut. This was followed up by Mods Carve The Pig: Assassins, Toads and God's Flesh. 1996′s Outer Space Is Just a Martini Away subsequently saw a significant change in the band's sound and lineup when Donaldson was replaced by

Jared Bryant. Oberlin switched to guitar and Bassist Herb Ledbetter was added. Thought Industry continued to strip down their lineup and sound with 1997′s moody "Black Umbrella", which saw the departure of Lee. Bryant, Enzio and Ledbetter also left the band in 1999 which prompted Oberlin to assemble an entirely new lineup for 2001′s magnum opus Short Wave on a Cold Day. Engineer Mike Roche, who recorded Black Umbrella and filled in on bass from time to time, was added as a full time guitarist along with drummer Cameron Taylor, bassist Mark Baldwin and guitarist/keyboardist Jeff Borkowski.
