The memorial was attended by numerous members of rock royalty, including Dave Grohl of the Foo Fighters, Dave Navarro of Jane's Addiction, singer-songwriter Joe Walsh and James Hetfield and Lars Ulrich of Metallica. The ceremony opened with the playing of one of Cornell's most recent songs, "The Promise."
The 52-year-old rocker died last week in Detroit after performing a show with Soundgarden. Officials said a preliminary autopsy showed he hanged himself, but toxicology tests are pending.
He is being laid to rest Friday at the Hollywood Forever Cemetery. A public memorial service is scheduled to begin at 3 p.m. PT.
