Soundgarden's Chris Cornell has died at age 52

This is breaking news - more to come.

From Newshub:

Soundgarden frontman Chris Cornell has died suddenly in Detroit, according to a representative.

He was 52.

Cornell was an iconic part of the grunge-rock genre forged in the 1990s, a member of three legendary bands - Soundgarden, Audioslave and Temple of the Dog.

At the time of his death he was in touring with Soundgarden and his final tweet was about their show in Detroit, sent just eight hours earlier.

The death was called 'sudden and unexpected', and a cause of death is currently unknown.

His unexpected death comes in the middle of Soundgarden's latest tour, with a further, sold-out show originally planned on Thursday (local time) in Ohio and others following until the end of May.

Representative Brian Bumbery said in a statement Cornell died on Wednesday night in Detroit, saying it was "sudden and unexpected".

His wife and family have been shocked by his death and will be "working closely with the medical examiner to determine the cause", Mr Bumbery said.

"They would like to thank his fans for their continuous love and loyalty and ask that their privacy be respected at this time."

As the lead singer for Soundgarden and later Audioslave, Cornell won two Grammy awards, for Best Metal Performance in 1995 and then Best Hard Rock Performance in 1995.

He and his band were nominated for a total of 14 Grammy awards between 1990 and 2011.

UPDATE: 

Chris Cornell's death ruled a suicide.

Tributes flow for Chris Cornell

The death has left the music world in shock.

Fellow musician Dave Navarro, formerly of the Red Hot Chili Peppers, tweeted that he was "stunned" to hear the news.

From us here at The Rock.....we're absolutely devastated. Many of us grew up listening to and idolising this man, from his Temple of the Dog days all the way to his time with Soundgarden and Audioslave. Truly gutted to hear the tragic news tonight.

Rest in peace, Chris Cornell.
