Neurosis is an American post-metal band from Oakland, California. It was formed in 1985 by guitarist Scott Kelly, bassist Dave Edwardson, and drummer Jason Roeder, initially as a hardcore punk band. Chad Salter joined as a second guitarist and appeared on the band's 1987 debut Pain of Mind and then Steve Von Till replaced him in 1989. The following year, the lineup further expanded to include a keyboardist and a visual artist. Beginning with their third album Souls at Zero (1992), Neurosis transformed their hardcore sound by incorporating diverse influences including doom metal and industrial music, becoming a major force in the emergence of the post-metal and sludge metal genres.
