Bumbery called the death “sudden and unexpected,” and notes that a cause of death is unknown at this time. The rep said that Cornell’s wife and family are shocked by the news and asking for privacy.

"They would like to thank his fans for their continuous love and loyalty and ask that their privacy be respected at this time," Bumbery said in a statement. 

Police are investigating Cornell's death as an apparent suicide, a spokesperson for the Detroit Police Department tells ET.

Cornell was one of the biggest voices in the ‘90s grunge movement. Though Soundgarden disbanded in 1997, they reunited in 2012. He also fronted the group Audioslave, which disbanded in 2007.

In addition to his work with these groups, Cornell also released four solo albums and a live album of his own work.

Shortly after the news of Cornell’s death hit the Internet, fellow musicians and fans took to Twitter to honor him.

Actor Will Sasso wrote, “His voice pulverized all classification, forever otherworldly. My heart goes out to his family. RIP Chris Cornell.”
