The widow of Soundgarden singer Chris Cornell led the tributes during a star-studded concert in his memory.
Cornell, a major figure in the grunge-rock scene of the 1990s, died in Detroit in 2017 aged 52.
Soundgarden, formed in Seattle in 1984, were among the first groups to rise to prominence in a wave that later included Nirvana, Pearl Jam and Alice In Chains.
On Wednesday, acts including Metallica, the Foo Fighters and Miley Cyrus performed at The Forum in Los Angeles during a tribute concert titled I Am The Highway.
Cornell’s widow, Vicky, with whom he had two children, appeared emotional as she took to the stage to pay tribute to her husband.
She said: “We all know how music can change us, but Chris did something more extraordinary – he changed music and paved the way for so many from Seattle to across the globe.
“And that legacy, and his influence, will live for generations to come. I am so proud that, along with his legacy, his philanthropic work continues to grow and flourish.
“Chris would be so very proud. Simply put, to me, and because of all of you, Chris lives on, a music immortal whose passion for helping others is more alive today than ever.”
Cornell’s daughter, Toni, 14, received a standing ovation after performing a cover of Bob Marley’s Redemption Song while standing in front of a picture of her father.
Actor Jack Black, himself a musician, said Cornell’s voice “could open a portal to another dimension”.
Cornell also fronted the super-groups Audioslave with members of Rage Against The Machine and Temple Of The Dog with members of Pearl Jam.
In October, a bronze statue of Cornell was erected outside the Museum Of Pop Culture in Seattle.
A coroner ruled that he took his own life and toxicology tests revealed he had a cocktail of drugs in his system at the time of his death, though the post-mortem examination report said they were not the cause of his death.
