Chris Cornell, who sang the signature tune for the James Bond film Casino Royale, committed suicide, according to an official investigation into his death.
The Soundgarden frontman, 52, was found dead in his hotel room on Wednesday night, reportedly with something around his neck.
Wayne County Medical Examiner’s Office said in a statement on Thursday afternoon: “The cause of death has been determined as hanging by suicide.
“A full autopsy report has not yet been completed.”
A video has emerged of his last performance in Detroit on Wednesday night of him jokingly looking ahead to the band’s next show.
Soundgarden were scheduled to headline Rock on the Range in Columbus, Ohio, Friday night. The festival has promised to celebrate Cornell all weekend.
He was a founder member of the Seattle grunge band and later teamed with three members of Rage Against the Machine in the guitar-driven Audioslave.
His gritty vocals on You Know My Name for Casino Royale, Daniel Craig’s debt outing as 007, helped introduce a new era of James Bond away from the tongue-in-cheek camp tone of the earlier films and their big band classics.
He also sang Live to Rise on The Avengers soundtrack, and the track The Promise for the recently released film of the same name, starring Oscar Isaac and Christian Bale.
Cornell’s representative Brian Bumbery said his death was “sudden and unexpected.”
