System of a Down
Khachaturian was born to Armenian parents in Los Angeles, California. He met Daron Malakian and Shavo Odadjian in high school. He then met Serj Tankian when they decided in 1994 to form the band System of a Down. Together, they recorded a demo titled "Untitled 1995 Demo" and "Demo Tape 1". In 1996, they recorded "Demo Tape 2" and "Demo Tape 3" and in 1997, recorded "Demo Tape 4". In 1997, after spending three years with System of a Down, Khachaturian had to leave the band due to an injury inflicted while practicing Jeet Kune Do after punching a hole in the wall and breaking every bone in his hand. He was replaced by John Dolmayan, the current drummer of System of a Down.
