The Suicide Machines were a band formed in 1991 in Detroit, Michigan under the original name Jack Kevorkian and the Suicide Machines. The band's original lineup consisted of Jason Navarro on vocals, Dan Lukacinsky on guitar, Jason Brake on bass, and Stefan Rairigh on drums. This lineup lasted a year until Bill Jennings replaced Rairigh, but he was himself soon replaced by Derek Grant. They recorded the band's first demos The Essential Kevorkian and Green World in 1993 and 1994, both released through their own label Sluggo's Old Skool Records. They also released the "Vans Song" 7" single on Youth Rendition Records. Brake left the group in 1994 and was briefly replaced by Dave Smith until Royce Nunley joined as the new permanent bass player. The lineup of Navarro, Lukacinsky, Nunley, and Grant would last for the next four years. This lineup reduced the band's name to The Suicide Machines and recorded the Skank for Brains split album with The Rudiments.
