“It’s with unbelievable sadness that we announce to our worldwide hardcore family the passing of our brother Lou Koller,” they began.

“The level of loss that we feel at this time is overwhelming.”

They shared that this year marks Sick of it All’s 40th anniversary as a band and honoured Koller’s “camaraderie, commitment and enthusiasm” throughout the decades.

“We have lost a beloved friend and an iconic frontman.

“Lou had the power to raise everyone’s spirits at our shows with a smile and a sarcastic comment, and he won people over wherever we played, from every culture and every corner of the world.”

Despite their “intense grief” the band thanked all those who supported and donated to Koller’s medical fund as he battled cancer.

They concluded the tribute with this parting message: “His battle is over now and he can finally rest. Hopefully he can somehow still see and feel the beautiful, positive mark he left on the world.”

Koller revealed in June 2024 that he was suffering from cancer of the esophagus which extended into his stomach. His illness forced the band to cancel a European tour while he underwent treatment.
