Los Angeles "punk" band AMEN, led by the enigmatic, energetic, and perennially self-destructive frontman Casey Chaos, will reform for a one-off performance at this year's Alt-Fest.Scheduled to take place August 15-17 at Boughton Estate, Kettering, Northamptonshire, United Kingdom, Alt-Fest will feature additional appearances by MARILYN MANSON, ARCH ENEMY, THE CULT, CRADLE OF FILTH and many more. Head to www.alt-fest.com for the full lineup and ticket details. AMEN's last collection of new studio recordings, "Death Before Musick", was released in 2004 through EatUrMusic — a Columbia Records imprint owned by SYSTEM OF A DOWN guitarist Daron Malakian. Maxwood Music Limited, a British publishing company which was assigned the rights to Casey's works, sued SYSTEM OF A DOWN in 2008 claiming that Casey co-wrote the SOAD song "B.Y.O.B." with Malakian. In May 2010, a United States District Court judge ruled that Malakian and SYSTEM OF A DOWN singer Serj Tankian are the sole authors of the song and denied Maxwood Music Limited's claim of ownership rights. Chaos made headlines in July 2012 when he was arrested for DUI in Studio City, California after he allegedly smashed his SUV into as many as 15 parked cars. Casey announced in August 2008 that he was making "much-needed and overdue changes to his lifestyle" and checking himself into Hollywood's Wonderland rehabilitation center. For over a decade, Chaos claimed, he had been prescribed various meds for pain and treatment of his various health issues. These, combined with grueling touring schedules and heavy drinking while on the road, had worn on Chaos and caused his health and state of mind to deteriorate further.
