Neurosis is a post-metal band, based in Oakland, California. They formed in 1985 as a hardcore punk band, and their sound progressed towards a doom metal style that also included influences from dark ambient and industrial music as well as incorporating elements of folk music.
In late 1985, Scott Kelly, Dave Edwardson and Jason Roeder (formerly members of Violent Coercion) founded the band as a hardcore punk outfit, borrowing from British crust punk like Amebix.
In 1986 Chad Salter was added on second guitar, and in 1990, Simon McIlroy joined the band as a synthesizer/sampler. 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, and in 1995 Noah Landis, a childhood friend of Dave Edwardson, replaced Simon McIlroy as keyboardist.
