There was an outpouring of grief and gratitude in the Bay Area and around the world on Friday as musicians and music fans paid tribute to Grateful Dead founder Phil Lesh, who died at 84.

A post on his Instagram account said the musician “passed away peacefully this morning.”

The official X account for Lesh’s late bandmate Jerry Garcia and his estate posted a heartfelt memory of the bassist.

“We are devastated to hear that Phil is moving on to the next life. We will miss his sharp dry humor, wry smile and brilliant insights. Our hearts and our love go out to his beloved wife and family. He truly lived for them with all his being,” said a message attributed to the Garcia family and posted with a few photos of the two friends.

“PS say hi to Jerry,” the message added.

The progressive bluegrass group The Infamous Stringdusters also paid tribute to X.

“He was always so kind and welcomed us into the Terrapin group with open arms. His impact on us and on music as a whole cannot be overstated. He will be gratefully missed,” the post said.

Chuck D of legendary hip-hop group Public Enemy paid tribute with a sketch and a simple sentence: “Phil Lesh keep it going.”

San Francisco Mayor London Breed posted a tribute to the bassist on X.

“Phil Lesh was more than a bassist: he was a San Francisco icon who helped define an era and shape the music world,” Breed wrote. She also noted that City Hall would be illuminated in Lesh’s honor Friday evening.

The San Francisco Giants posted about Lesh, calling him “a true San Francisco legend and a beloved part of our #SFGiants family. His unforgettable music and presence at Oracle Park will live on forever.”

Tributes were also posted by venues across the country where the Grateful Dead and Lesh had performed with his own group Phil and Friends, including New York’s Madison Square Garden. The Empire State Building was even lit up in tie-dye colors to pay tribute.
