Imperative Reaction is an electro-industrial band founded in 1996 by Ted Phelps and David Andrecht from the remains of the band Digital Neural Assault.
A demo tape titled Debris was originally released in 1996, but was eventually recalled and destroyed as the band chose to go a different direction. The band's next effort, a demo entitled Persistence of Memory, featured the track "Predicate", which was included on Possessive Blindfold Recordings compilation album Exoskeleton Vol. 1.
The band's first studio album, Eulogy For The Sick Child, was released in February 1999. The next month, it had reached the top ten of CMJ's (RPM) charts. The popularity of the album in the United States caused Zoth Ommog Records to pick it up for European distribution in April 1999. In the summer of 1999, the band changed labels, due to the buyout of Pendragon Records by Metropolis Records.
