Author Benedetta Baldin - 25.7.2026

Lou Koller, the singer of Sick Of It All, has sadly passed away, as per theprp. After receiving a diagnosis of an esophageal tumour in 2024, the 59-year-old singer heroically fought cancer. His cancer returned last autumn despite early therapies showing improvement, and he said in December of last year that he and the illness were at a “stalemate.” On July 24, his comrades sadly revealed that the cherished hardcore frontman had passed away. Our deepest condolences to his friends, family and loved ones.

It’s with unbelievable sadness that we announce to our worldwide hardcore family the passing of our brother Lou Koller. The level of loss that we feel at this time is overwhelming. This year would have marked Sick of it All’s 40th anniversary as a band, and Lou’s camaraderie, commitment and enthusiasm were always steadfast throughout the years. 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.
At this time of intense grief, we must again acknowledge the great help and support offered by everyone who donated to Lou’s medical fund. You all helped Lou feel very special and very loved as he battled away these last two years. 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.

The American hardcore punk rock group Sick of It All was founded in Queens, New York City, in 1986.

Sick of It All had sold at least 500,000 records globally by 2020 and is regarded as a significant component of the New York hardcore movement.
