Lou Koller was born on July 15, 1965, in Queens, New York, where he was raised alongside his three brothers, including future Sick of It All guitarist Pete Koller. Growing up, he developed an interest in heavy music, citing bands like Black Sabbath, Motörhead, and Judas Priest as early influences. He attended Francis Lewis High School, where he worked in a theatre to earn sound engineering credits.

In 1986, while still in high school, Koller and his brother Pete formed Sick of It All. Initially playing bass and vocals, Koller soon became the band's dedicated frontman. The band released their debut EP in 1987 and their first full-length album, Blood, Sweat and No Tears, in 1989, which became a landmark record in the hardcore genre. Their 1994 album Scratch the Surface sold over 250,000 copies worldwide and helped bring New York hardcore to international audiences. Over four decades, Sick of It All released twelve studio albums and became one of the most influential bands in hardcore punk history.

Koller was known for his gravel-throated vocal style and lyrics addressing community, politics, and social issues. He also formed the side project Blood from the Soul with Napalm Death's Shane Embury in 1993. In 2021, he and his brother published an autobiography, The Blood and Sweat: The Story of Sick of It All's Koller Brothers. Koller battled esophageal cancer, first diagnosed in June 2024. Despite a brief remission, the cancer returned, and he died on July 24, 2026, at age 61.
