EMS workers pronounced Cornell dead at the scene.
Soundgarden had been the first band from Seattle's grunge scene to get signed to a major label and helped pave the way for bands like Nirvana, Pearl Jam and Alice in Chains to become the new forebears of rock music. After Soundgarden broke up in the late Nineties, he pursued a solo career. Producer Rick Rubin ended up recruiting Cornell for the band Audioslave — a project pursued by the remaining members of Rage Against the Machine following the departure of singer Zack de la Rocha — and Cornell achieved even greater success, singing on radio hits "Like a Stone" and "Cochise."
In 2010, Soundgarden reunited for new live dates and released what appears to be their final album with Cornell as lead vocalist, 2012's King Animal.
