Casey Chaos

Disorderly Conduct released one album — "Amen" — and were featured on various contemporary compilations, both on cassette and vinyl; the band included long-term associate U.S. Ken Decter (later Duke Decter) on guitar.

In 2012 Chaos collaborated with Ross Robinson again for a movie documentary entitled House Of Shock, also featuring Dave Lombardo of Slayer fame on drums and Gary Holt of Exodus on guitar.

Chmielinski was arrested in Los Angeles on July 5, 2012 after he allegedly smashed his SUV into parked cars in the Studio City area of Los Angeles. Some reports indicated that as many as fifteen vehicles were allegedly hit, but a more accurate statistic appears to be three. Police state that the musician abandoned his vehicle after causing the destruction but they were able to track him down at his home. After testing, the musician registered a blood alcohol level just above .08 — the legal limit in California. Although a neighbor witnessed the entire alcohol test and said, "he was stumbling all over the sidewalk", the reading reveals that Chaos had consumed slightly upwards of a single beer in what was curiously publicized as an alleged "drunken demolition derby".

In 2007, Amen performed on Season 2 of The Henry Rollins Show.

In 2006, Chaos performed with Rat Scabies and Brian James, former members of original 1976 English punk band the Damned to celebrate the 30-year anniversary of the release of their debut album Damned Damned Damned, by performing the album in its entirety at London's historic 100 Club. In the same year, Casey Chaos received a Grammy Award Certificate for co-writing "B.Y.O.B." for the band System of a Down. The credit was revoked in 2010 after a court case precipitated by Chaos' selling some of his interest to a third party.

In 2004 Casey Chaos began a side project consisting of Chaos, black metal icons Samoth and Bård Faust from Emperor, and Happy Tom from Turbonegro, and in 2005 Scum's Gospels for the Sick was released., and the album was nominated for the Alarm Awards (Norwegian music awards) in the metal category, but lost to Stonegard. The album also has guest appearances including Mortiis and Nocturno Culto of Darkthrone.

In 2003 the band was once again released from their existing contract. Upon hearing this Daron Malakian of System of a Down sought to sign the band as his first acquisition for his newly created imprint label with Sony BMG, EatUrMusic Records. The label released Amen's Death Before Music in 2003, and a video for the single "California's Bleeding".

In 2003, Chaos collaborated with EatUrMusic label partner Daron Malakian to form a side project called Scars On Broadway.

As Disorderly Conduct began negotiating with Metal Blade Records for the release of their new recording Atrocity, Chaos and band guitarist Duke Decter moved to California and changed the name of the band to the title of their first album, Amen. Upon meeting Rikk Agnew (Adolescents, D.I., Christian Death), Amen was briefly put into hibernation while the pair began a musical collaboration which led to Chaos playing bass for a short tour with the reunited original Christian Death. Afterwards, Chaos returned to Amen and recorded Slave, a full length independent album which led to a record deal with Roadrunner Records and the 1999 official debut release of Amen's self-titled album Amen. As the notorious actions of Casey Chaos and his band grew during the subsequent tour, Roadrunner released the band from their contract and they were swiftly picked up by Virgin Records. Casey Chaos and band found a home at their new label, which strongly pushed and promoted the band, leading to the release of their second album in 2001, the highly successful We Have Come For Your Parents, also produced by Ross Robinson.
