Brad Arnold, lead singer of the rock group 3 Doors Down and their hit “Kryptonite,” has died at the age of 47, seven months after revealing he was battling stage 4 cancer. This’ll be a battle so we need our prayers warriors!”The Mississippi-born Arnold formed 3 Doors Down in 1996 with high school buddies guitarist Matt Roberts and bassist Todd Harrell in their hometown of Escatawpa, with Arnold serving as both singer and drummer. The following year, the trio recorded their first demo tape, featuring a track titled “Kryptonite” that Arnold said he penned while still in high school. The band’s follow-up, 2002’s Away from the Sun, found Arnold shifting strictly to vocalist, with drummer Josh Freese recruited for that multiplatinum LP. Arnold is the second original member of 3 Doors Down to die: In 2016, Roberts, who co-wrote “Kryptonite” with Arnold, died following a drug overdose.
