Chris Cornell’s brother Peter paid tribute to the late musician in a touching letter posted to Facebook earlier this week where he said his “heart is broken” and thanked well-wishers for their “kindness and condolences.”

“It wasn’t until this week, it really hit me how he belonged to the world,” Peter wrote. “That he is an icon and a legend. That being said, I am so sorry to YOU for your loss. Artists, actors, musicians. We rely on these people to lift us up. To inspire us and distract us in times of trouble. Chris protected us when we needed him to. His one of a kindness surrounded us like a suit of armor. He was a warrior and a wizard. A howling wolf and a trusted mentor.”

Chris died by suicide May 17 at the age of 52. Throughout his decades-long career, the musician fronted Soundgarden, Temple of the Dog, and Audioslave, and released five albums as a solo artist.

“My brother gave freely of his gifts and it was never a struggle,” Peter continued in his note. “He kept himself from the saturation of celebrity in such a humble way. The power and anger and passion of my brother’s music was always genuine, original and legitimate. He was the powerful, sensitive, fragile, angry, mystical creature that will exist forever in his body of work. And he did it for ALL of us. Giving it away. Leaving all on the stage or in the recordings that will keep him immortal.”

Peter also included two photos of him and Chris. See the full post above.
