Lead singer died on Saturday, months after he announced that he had been diagnosed with stage 4 kidney cancer

Brad Arnold, the lead singer of the Grammy-nominated rock band 3 Doors Down, has died, months after he announced that he had been diagnosed with stage 4 kidney cancer. He was 47.

The band said in a statement on Saturday that Arnold “passed away peacefully, surrounded by loved ones, in his sleep after his courageous battle with cancer”.

3 Doors Down formed in Mississippi in 1995 and four years later received a Grammy nomination for the breakout hit Kryptonite. Arnold wrote the song in math class when he was 15 years old, according to the band statement.

Their debut album, The Better Life, sold more than 6m copies. A second Grammy nomination came in 2003, for the song When I’m Gone.
