Insanity is an American death/thrash metal band formed in San Francisco, California in 1985. Their demo cassette from October of the same year is considered one of the earliest death metal recordings. Following the tragic passing of their original vocalist Joe DeZuniga in 1987, Insanity disbanded until 1989. Founder and guitarist Dave Gorsuch would resurrect the group multiple times since then, with the band eventually releasing a couple of studio albums over the years.
