Brad Arnold, co-founder and lead singer of the rock band 3 Doors Down, has died at the age of 47 after a courageous battle with cancer. The band announced his passing on Saturday, revealing that he was surrounded by loved ones, including his wife, Jennifer. Arnold's health had been deteriorating since he disclosed in May 2025 that he had been diagnosed with stage 4 clear cell renal carcinoma, a type of kidney cancer that had metastasized to one of his lungs, forcing the cancellation of their summer tour that year, according to CBS News, Reuters, and BBC.

The band 3 Doors Down, formed in 1996 in Mississippi, gained fame in 2000 with Arnold's hit single "Kryptonite," which peaked at No. 3 on the Billboard Hot 100. Their other well-known tracks include "When I’m Gone" and "Here Without You," which also reached top-five positions. "Brad helped redefine mainstream rock music, blending post-grunge accessibility with emotionally direct songwriting," the band stated, emphasizing his significant impact on the genre, according to Reuters and BBC.

Arnold was not only cherished for his musical talents but also for his personal qualities. His band's statement highlighted his warmth, kindness, and faith, stating, "Those closest to him will remember not only his talent but his warmth, humility, faith, and deep love for his family and friends." Arnold had also shared his personal struggles with alcoholism, reflecting on his sobriety since 2016, which he credited positively towards enriching his life, according to CBS News and BBC.
