In 1986 Chad Salter was added on second guitar and vocals. There have only been a few changes in the lineup of Neurosis' musicians since band's inception. In 1989 guitarist/vocalist Chad Salter was replaced by Steve Von Till, who previously played in bands Transgressor, Peace Test and Tribe of Resistance, and in 1990, Simon McIlroy joined the band as a synthesizer/sampler with Adam Kendall as visual artist (Adam and Simon have been friends since they were teenagers and they were doing a lot of experimental music together before). In 1995 Noah Landis, a childhood friend of Dave Edwardson, replaced Simon McIlroy as keyboardist.
