Last Friday (July 24), New York City group Sick of It All confirmed that singer Lou Koller has passed away at the age of 59. Since then, many fellow rockers and dedicated fans have paid tribute to the hardcore punk vocalist.

Sick of It All’s Statement on Lou Koller’s Passing

Sick of It All announced the tragic news via Instagram on July 24, beginning: “It’s with unbelievable sadness that we announce to our worldwide hardcore family the passing of our brother Lou Koller.”

Their statement continued:

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.

Per Rolling Stone (on July 24), Koller “had been battling adenocarcinoma cancer.” In particular, the magazine clarified, Koller “shared with fans [in June 2024] 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.”

As The Guardian noted, Koller’s illness “forced the band to cancel a European tour while he underwent treatment. . . . After intensive treatment, including chemotherapy, Koller was declared cancer-free in May 2025, but the cancer returned shortly after.”

Of course, everyone at Loudwire shares our condolences with Koller’s family, friends and fans.

Man, I am so sorry to hear that, from all of us in Machine Head our deepest condolences

I do have one really funny story though from when we played a festival with them… Some dude was flipping Lou off, and he went over to him and he said “hey you, stop flipping me off, or you’re gonna get a skinny little finger poked right in your fucking eye”… man, I laughed so fucking hard… All these years I still remember that

RIP legend

More About Sick of It All + Lou Koller

Koller founded Sick of It All with his guitarist brother, Pete, in 1986, and they quickly became a huge part of New York City’s hardcore scene.

Throughout their career, they went through numerous lineup changes as the Koller brothers continued steering the ship, and they released 12 studio LPs (from 1989’s Blood, Sweat and No Tears to 2018’s Wake the Sleeping Dragon!). Their breakthrough third full-length record – Scratch the Surface – came in 1994, and they’ve toured with major acts such as Korn, Napalm Death, Sepultura and Avenged Sevenfold.

As Loudwire reported in 2022, Sick of It All may’ve created the legendary “wall of death” most pit, and they were a highlight of the first-ever Warped Tour in 1995. Plus, Killswitch Engage’s Jesse Leach once named “We Stand Alone” (from 1991’s We Stand Alone EP) the greatest hardcore song ever.

“That song encapsulates why I love hardcore and punk,” he explained. “It’s a total protest song. When I was younger, looking for my identity, I didn’t fit in with the mainstream, I didn’t fit in with the cool kids, I didn’t fit in with all these people. Sick of It All were one of those bands that made me proud.”

In mid-2025, and following Koller’s aforementioned cancer-free diagnosis, Sick of It All guitarist Craig Setari confirmed that the band were “planning to get together and start working on [a new album]” and “potentially play some shows [in 2026].” However, Koller’s cancer returned shortly thereafter, prompting the “A Benefit for Lou Koller” benefit show that took place earlier this year.

Outside of Sick of It All, Koller co-founded industrial metal supergroup Blood from the Soul alongside Napalm Death’s Shane Embury. They disbanded in 1993 but reformed in 2020 without Koller (but with Embury, Converge’s Jacob Bannon, Megadeth’s Dirk Verbeuren and Jesper Liveröd).

Beyond that, both Koller brothers were tour guides at the Punk Rock Museum in Las Vegas.
