The tweet was posted at 8:06pm Eastern time and showed the marquee in Detroit just before his last show. At just 52-years-old, we assumed Cornell had a long life ahead. Brian Bumbery, a representative for Cornell, told the Associated Press that his death was “sudden and unexpected.”

Update, 6:03am: Local news in Detroit are reporting that it was a possible suicide:

Aside from Cornell’s own tweets, we also have the social media posts of fans who saw last night’s Soundgarden concert.

Chris Cornell was a huge part of my teenage years as I was discovering rock music in the mid-1990s. And I loved the music that would come to be regarded by the previous generation, Generation X, as not nearly as cool as Soundgarden’s “earlier work.”

The 1996 album Down on the Upside was derided by critics, and Cornell’s first solo album, 1999's Euphoria Morning, was considered deeply uncool. But to me they were magic. They were the soundtrack of a depressed teenager who had narrowly missed the “cool” era of grunge in the early 90s. Even after Soundgarden split in 1997, Cornell continued making amazing music for kids like me.

Naturally, people are taking to social media to mourn in their own ways. The cause of death has not been determined and the Cornell’s family has asked for privacy.

RIP Chris Cornell.
