Steve Harwell, the lead singer of the band Smash Mouth, died on September 4, 2023, at the age of 56. The cause of death was acute liver failure. Harwell had been struggling with several health issues for years, including cardiomyopathy (a heart condition) and Wernicke encephalopathy (a neurological disorder affecting speech and memory). He also had a history of addiction and alcoholism, which contributed to his declining health. Harwell retired from performing with Smash Mouth in 2021 after a problematic onstage appearance and spent his final days in hospice care at his home in Boise, Idaho, surrounded by family and friends.
Smash Mouth is still an active band, with a new lead singer having taken over after Harwell's retirement.
