Former Smash Mouth singer Steve Harwell has died, a representative for the band confirms to Billboard.

Harwell, who performed as lead vocalist for the California pop-rock act until announcing his retirement from the group in 2021, passed away Monday (Sept. 4) at his home in Boise, Idaho, after being in hospice care. He was 56.

“Steve Harwell passed away this morning September 4, 2023 at his home in Boise Idaho. He was surrounded by family and friends and passed peacefully and comfortably,” reads a statement provided by Smash Mouth manager Robert Hayes.

“Steve Harwell was a true American original. A larger than life character who shot up into the sky like a Roman candle. Steve should be remembered for his unwavering focus and impassioned determination to reach the heights of pop stardom. And the fact that he achieved this near-impossible goal with very limited musical experience makes his accomplishments all the more remarkable,” the statement continues.

Leading up to his death, Harwell was being cared for at home by his fiancé and hospice care. TMZ first wrote of the musician’s current health status earlier on Sunday (Sept. 3), reporting that he’s reached the final stage of liver failure.

Harwell was diagnosed with cardiomyopathy, a disease of the heart muscle that can makes it hard for the heart to deliver blood to the body, several years ago. Following his initial diagnosis, he suffered from “nonstop serious medical setbacks including heart failure as well as acute Wernicke Encephalopathy,” a condition that greatly impacted his motor functions, including speech and impaired memory, a statement said in 2021.
