The band announced his death on Friday in a social media post. “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,” wrote the group, which noted this year would have marked Sick of it All’s 40th anniversary together. The singer’s age and date of death were not immediately available.
His fellow bandmates praised Koller’s “camaraderie, commitment and enthusiasm” that remained “steadfast throughout the years.” “We have lost a beloved friend and an iconic frontman,” they continued. “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.”
In June 2024, Koller shared with fans that doctors had found a tumor in his esophagus that went into his stomach, and that he would have to pause touring to undergo treatment.
