Chris Cornell exhorted a packed house at his final gig in Detroit to sing backing vocals and make some noise.

Rolling Stone called it a "muscular" performance - but one reporter in the crowd said Cornell wasn't "mentally present" for his final time on stage.

Hours after the sold-out gig with his original band, Soundgarden, at the Fox Theatre, Cornell was found by a friend, dead on the bathroom floor of his room at the MGM Grand Hotel. He was 52 years old.

A medical examiner later ruled he had died by suicide.
