Brad Arnold, lead vocalist and co-founder of the rock band 3 Doors Down, has died at the age of 47, according to a statement released by the band on Saturday.
The group said Arnold passed away peacefully in his sleep after a battle with cancer. He was reportedly surrounded by his wife, Jennifer, and close family members at the time of his death.
Arnold was a founding member of 3 Doors Down, originally serving as the band’s drummer before transitioning to lead vocalist. The band rose to major international success in the early 2000s with hits such as “Kryptonite,” “Here Without You,” “When I’m Gone,” and “It’s Not My Time.”
According to the statement and reports, Arnold was diagnosed in May 2025 with Stage 4 clear cell renal cell carcinoma, a form of kidney cancer that had reportedly spread to his lungs. Following his diagnosis, the band canceled upcoming tour plans scheduled to begin in Daytona Beach, Florida.
Arnold’s songwriting career began at a young age. He wrote the breakout hit “Kryptonite” at just 15 years old, a track that helped launch the band’s debut album The Better Life into multi-platinum success and established them as a defining act in post-grunge rock.
