The Amen frontman - who was also a member of Christian Death and Scum, and a former professional skateboarder - passed away on Saturday (21.12.24) at the age of 59, his record label, Cleopatra Records, have announced, though they didn't give any information about the details of his passing.

They said in a statement: "It is with great sadness that Cleopatra Records announce the passing of Casey Chaos, one of the most exciting, and individual punk and metal performers of the last 30 years, and one of the very few, too, to have received a Grammy award."

A statement on the band's own Facebook page promised the group would be looking for ways to offer a fitting tribute to their friend's memory.

It read: "It is with great sadness, grief and sorrow that we confirm the passing of Casey Chaos after seeing the news currently being reported.

"As you can imagine, everyone in the band, past and present, are absolutely devastated.

"There was a lot going on with AMEN in the past 5-6 years that we didn't announce. Casey loved and appreciated your support, and always wanted to wait until things were complete, rather than sharing unfinished work-in-progress material.

"The rest of us are going to reflect on the ways we can honour Casey in the way he deserves; to have his genius, talent and heart celebrated and experienced by the world and the people who appreciated it.

"Please share any positive memories you have about Casey on this post...

Cleopatra Records boss Brian Perera hailed working with the "extraordinary" musician - whose real name was Karim Chmielnski - a "privilege".

He said: "I had the privilege of working with Casey during his unforgettable live performance with Christian Death at the American Legion Hall back in 1993. Walking into the hall with my good friend Matt Green and my wife, Yvonne, was an experience I'll never forget--especially seeing Nicolas Cage sitting front-row centre, completely captivated...

"Casey wasn't just an extraordinary musician. He truly lived and breathed the lifestyle.

"May he rest in peace alongside Rozz Williams and the many tortured souls we admire and respect."

Amen bassist John Fahnestock remembered his bandmate as a "legend" and a "genius".

He posted on Instagram: "With a heavy heart and a tear in my eye I must announce that we lost another legend today.

"I've lost two legendary frontmen in my career and Casey has now also passed on.

"It was an absolute honour to have been in AMEN and witnessed without a doubt the genius that was Casey Chaos. He was a force unlike no other before him, a true artist, an uncompromising soul and a true punk rock icon!

"This is hard for me. I sit here going over all the memories just speechless .... #caseychaos #amen #legend #legendary #legendsneverdie #icon #punkrock #punkrocklegends"(sic)"
