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.
