Lou Koller, the frontman of the longstanding New York hardcore band Sick Of It All, has died. The vocalist and co-founder revealed in 2024 that he had been diagnosed with esophageal cancer. The band announced his passing on social media yesterday. He was 59.
"It’s with unbelievable sadness that we announce to our worldwide hardcore family the passing of our brother Lou Koller," the statement begins, continuing:
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.
Lou Koller was born in Queens, New York, where he co-founded Sick Of It All in 1986 with his brother Pete on guitar. They emerged from the same scene that nurtured Agnostic Front, Cro-Mags, and Madball, and their 1989 debut Blood, Sweat And No Tears remains a classic in the genre. The band would undergo several lineup changes over its 40 years, during which they released 12 studio albums.
Upon the announcement of his diagnosis in 2024, the scene rallied together to host benefit concerts. In May 2025, he revealed he was cancer-free after a final round of chemotherapy, but it returned months later.
