The singer said, "Although tonight is a time to celebrate the music and artists of the past year, it's also a time to remember someone we lost this week".
As if you need reminding, Chris Cornell - grunge pioneer, vocal powerhouse and all-around music legend - tragically passed away on May 17th, 2017. His wife, Vicky, said in an emotional statement, "Chris's death is a loss that escapes words and has created an emptiness in my heart that will never be filled".
Audioslave disbanded in 2007, but Cornell and Soundgarden reunited in 2010 and released the band's sixth studio album, "King Animal" in 2012.
Martin, who was working as a personal bodyguard for the Soundgarden frontman, had stopped by Chris' room at 11:30pm to fix the singer's computer. His last tweet, sent Wednesday just after 8 p.m., paid respect to "Rock City", and has been retweeted some 13,500 times since.
However, a full autopsy was yet to be done. In 2001, Cornell joined with three former members of Rage Against the Machine to form Audioslave.
The service will be private but his family's attorney Kirk Pasich has revealed that 'one or more public memorials will be considered'.
During U2's performance at the Rose Bowl in LA singer Bono dedicated their song "Running to Stand Still" to Cornell and his family.
The Detroit News obtained a police report which states that Kirsten gave Cornell two Ativan pills to combat anxiety after he came to his hotel room to fix his computer following his concert in Detroit on Wednesday night.
Cornell began his career in the Seattle rock scene.
The 52 year-old vocalist had a prescription for Ativan, the family shared, and may have taken a higher dosage that impaired his judgement.
