Steve Harwell, the former frontman of Smash Mouth, has died. He was 56.

Smash Mouth paid tribute to their former bandmatevia an Instagram postshortly after his death.

“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,” they wrote.

“And the fact that he achieved this near-impossible goal with very limited musical experience makes his accomplishments all the more remarkable. His only tools were his irrepressible charm and charisma, his fearlessly reckless ambition, and his king-size cajones.“The band continued, “Steve lived a 100% full-throttle life. Burning brightly across the universe before burning out. Good night Heevo Veev. Rest in peace knowing you aimed for the stars, and magically hit your target.”

TMZ wasfirst to reportthat the singer was in the final stage of liver failure after previously undergoing treatment for alcohol abuse at a hospital.

A source close to Harwell explained to PEOPLE in 2021 that the musician had “suffered profusely” with addiction over the years, which have led to some of his medical and mental health issues.

“Even though Steve has not been with Smash Mouth for two years now, and the band continues to tour with new vocalist Zach Goode his legacy will live on through the music,” Hayes told PEOPLE on Sunday.

“With Steve, Smash Mouth has sold over 10 million albums worldwide-wide and topped the charts with two No. 1 hit singles, five Top 40 singles, three Hot 100 singles, four Billboard 200 albums and a Grammy nomination not to mention the hundreds of film and television placements and of course those musical features inShrek.”

“Steve’s iconic voice is one of the most recognizable voices from his generation. Steve loved the fans and loved to perform,” added Hayes.
