In early 1995, System played as "Soil" at the Cafe Club Fais Do-Do, a nightclub in Los Angeles. Shortly after the event, System of a Down made what is known as "Untitled 1995 Demo Tape", which was not commercially released but appeared on file sharing networks around the time of the band's success with "Toxicity" about six years later. "Demo Tape 2" was released in 1996. At the beginning of 1997, System of a Down recorded their final publicly released demo tape, "Demo Tape 3". In mid-1997, drummer Khachaturian left the band because of a hand injury (he subsequently co-founded The Apex Theory, which included former Soil bassist Dave Hakopyan). Khachaturian was replaced by John Dolmayan.
