Cornell passed away in Detroit Wednesday night after performing with Soundgarden. Cornell's rep called his death "sudden and unexpected."
Local reports say that on Wednesday night, Cornell's wife was concerned about her husband's well-being. So she asked a friend to check on him in his hotel room. The friend reportedly forced his way in and found Cornell dead in the bathroom with something around his neck. Sources added that the death may have been a suicide, though that has not been confirmed.

Before his death, Chris Cornell was best known as one of the leaders of the Seattle grunge movement in the 1990s. He co-founded Soundgarden in 1984, and by the early 1990s, their songs could be heard on alternative radio stations.
Soundgarden then became a household name with the 1994 album Superunknown. The record was nominated for a Grammy, and songs like "Spoonman" and "Fell on Black Days" became mainstream hits. Another popular album, Down on the Upside, followed.
Watch one of Soundgarden's music videos below.
Soundgarden broke up in 1997 after reports of infighting amongst the band members. Cornell went on to front Audioslave, a supergroup that included former members of Rage Against The Machine.
Audioslave eventually disbanded, and in 2012 Cornell reunited with Soundgarden. That year, the group released another album. And in 2013, they went back on tour. They began their latest tour last month and had been working on a new record.
"We’re about halfway through writing the new album," Cornell told Billboard just weeks before his death. "We’re not on a schedule. What I look forward to the most -- because I tour so much, especially the last couple of years, by myself -- is the camaraderie. It’s what we missed when we weren’t a band. When I do solo tours, I’m really kind of alone all the time, so that’s the best thing about it."
Indeed, Cornell seemed excited about the group's tour. Hours before he died, he tweeted a photo of the Detroit theater where the band was about to perform.
