The music world was busy mourning David Bowie on the 10-year anniversary of his death on Saturday when the devastating word hit that we lost another icon of almost indescribable significance to rock history: Bob Weir. 

“He transitioned peacefully, surrounded by loved ones, after courageously beating cancer as only Bobby could,” the Weir family wrote in a public statement. “Unfortunately, he succumbed to underlying lung issues.”

The road was Weir’s home from the moment the Grateful Dead formed in 1965 all the way through last summer. His projects outside the Grateful Dead included RatDog, Furthur, Bob Weir and Wolf Bros, and Dead & Company. At almost any given time, he had shows on the books with at least one of them.

“The interesting thing is, I’ve never made plans,” he told Rolling Stone‘s Angie Martoccio last March. “And I’m not about to, because I’m too damn busy doing other stuff, trying to get the sound right, trying to get the right chords, trying to get the right words, trying to get all that stuff together for the storytelling. And really, making plans seems like a waste of time. Because nothing ever works out like you expected it to, no matter who you are. So why bother?”

Dead & Co. wrapped up a farewell tour in July 2023, but they continued to play residencies at Sphere in Las Vegas throughout 2024 and 2025. And they came together one last time in August 2025 for three shows in San Francisco’s Golden Gate Park to celebrate the Grateful Dead’s 60th anniversary. Throughout the three evenings, they were joined by Billy Strings, Trey Anastasio, Grahame Lesh, and Sturgill Simpson.

These were joyous concerts filled with Deadheads from around the globe, but Weir was holding a secret: He was diagnosed with cancer weeks earlier, and had just started treatment. “Those performances, emotional, soulful, and full of light, were not farewells, but gifts,” the Weir family wrote. “Another act of resilience. An artist choosing, even then, to keep going by his own design.”

The final night wrapped up with “Touch of Grey,” perhaps the most famous tune in the Dead songbook. Weir sang lead, and the band stretched it out for nearly eight minutes. At the end, Weir took a group bow with the full band, waved to the crowd, and then took a special bow with Mickey Hart, the only other original member of the Dead in Dead & Co., before they walked off together. It was his final live appearance. 

“There is no final curtain here, not really,” wrote the Weir family. “Only the sense of someone setting off again. He often spoke of a three-hundred-year legacy, determined to ensure the songbook would endure long after him. May that dream live on through future generations of Dead Heads. And so we send him off the way he sent so many of us on our way: with a farewell that isn’t an ending, but a blessing. A reward for a life worth livin’.”

It’s way too early to seriously contemplate the future of Dead & Co., but it’s somewhat hard to imagine them continuing outside of a tribute concert to Weir. He was the heart and soul of the group.

That said, Weir himself once said he hoped to see the band outlive him. “I had a little flash while we were playing one night,” Weir told Rolling Stone‘s David Fricke in 2016. “It was toward the end of the tour. I don’t remember what city it was in. We were getting into the second set, setting up a tune. We were all playing, but the tune hadn’t begun yet. We were all feeling out the groove, just playing with it. Suddenly I was 20 feet behind my own head, looking at this and kind of happy with the way the song was shaping up. I started looking around, and it was 20 years later. John’s hair had turned gray. Oteil’s had turned white. I looked back at the drummers, and it was a couple of new guys. I looked back at myself, the back of my head, and it was a new guy. It changed my entire perception of what it is we’re up to.”

The members of Dead & Co. will ultimately make the call. And no matter what happens, Grateful Dead music will continue to live on concert stages for decades and decades to come. They are responsible for a significant chapter of the Great American Songbook.
