Sad news for Audioslave and Soundgarden fans today, with news out of the US that singer Chris Cornell has passed away.

In a statement to The Associated Press, rep Brian Bumbery said the 52-year old rocker passed away “suddenly and unexpectedly” in Detroit.

The statement said the family would be working closely with the medical examiner to determine the cause and asked for privacy.

Cornell only posted on social media about eight hours earlier, tweeting about Soundgarden’s show in Detroit:
