Christian also performed backing vocals in Testament.

Career Testament Christian is an original member of Testament, having joined in 1983 when they were called Legacy. Prior the release of their debut album The Legacy, Christian auditioned for Metallica as the replacement for Cliff Burton, but lost to former Flotsam and Jetsam bassist Jason Newsted. He recorded eight of the band's albums, including The Legacy (1987), The New Order (1988), Practice What You Preach (1989), Souls of Black (1990), The Ritual (1992), Low (1994), The Formation of Damnation (2008), and Dark Roots of Earth (2012). He also played on their live albums Live at Eindhoven (1987), Return to the Apocalyptic City (1993), Live at the Fillmore (1995), Live in London (2005) and Dark Roots of Thrash (2013). In 1996, Christian left Testament, but rejoined in 2004. He left the band once again in early 2014 and was replaced by Steve Di Giorgio as bassist. Christian left due to lack of band financial transparency and inequitable payments by controlling members of Testament, Chuck Billy and Eric Peterson.

HavocHate Christian joined HavocHate in 2005, and recorded one album, Cycle of Pain.
