Bob Weir, a guitarist and singer-songwriter who was one of the founders of the popular and highly influential American rock band the Grateful Dead, has died at the age of 79.
According to a family statement, posted on his official website and social media pages, Vir died of lung problems, after recently beating cancer.
As a member of the Grateful Dead for its first three decades, and then as a flame-keeper for the band's legacy for another three decades, Weir helped write a new chapter in American popular music, influencing countless other musicians and amassing a huge and fiercely loyal following. The Grateful Dead's tours, toleration of concert recordings, and extensive merchandise sales set an example that helped spawn the jam band scene. Their concerts created a community that connected generations of followers, NPR recalls.
Known to fans as "Bobby", he was born Robert Hall Parber in San Francisco, but was given up for adoption and raised by his adoptive parents, Frederick and Eleanor Weir. In 1964, while still a teenager, Weir joined guitarist Jerry Garcia in the folk band Mother McCree's Uptown Jug Band. In May 1965, Weir and Garcia were joined by bassist Phil Lesh, keyboardist Ron "Pigpen" McKernan, and drummer Bill Kreutzmann to form a rock and roll band that briefly went by the name The Warlocks. After discovering that a band by that name already existed, Jerry Garcia found a term in a dictionary that caught his attention, and in December of that year they became the Grateful Dead, beginning a thirty-year run that would grow them into a cultural institution.
Vir was a unique rhythm guitarist who rarely played solos, choosing instead to develop his own style of chord and rhythmic playing, which he elegantly supported Garcia's signature guitar explorations, especially during the long jams that made the band popular.
The lyrics were largely the result of collaborative work between Weir and Garcia, as well as John Perry Barlow and Robert Hunter, often blurring the lines between who wrote what.
Vir's emotional singing, on songs like "Cassidy," "Sugar Magnolia," "One More Saturday Night" and the band's unofficial anthem "Truckin'," often included shouts and shouts, in contrast to Garcia's calm and steady approach. His occasional tendency to forget lyrics was usually met with thunderous applause from the audience, NPR reports.
After Garcia's death in 1995 at the age of 54, the surviving members of the band continued to perform in various forms and lineups, the longest-running of which was Weir's Dead & Company, featuring legendary guitarist John Mayer and Grateful Dead drummers Kreutzmann and Mickey Hart. Weir and the band completed their "final tour" in July 2023, but then returned to the stage for two extended residencies at the Sphere in Las Vegas, in 2024 and 2025.
A self-proclaimed “compulsive music maker,” Weir formed another band in 2018 to explore the depths of the Grateful Dead’s catalog. It was a stripped-down lineup—guitar, acoustic bass, and drums—called Bobby Weir & Wolf Bros., which also included renowned bassist and producer Don Vos. In October 2022, Weir & Wolf Bros. collaborated with a classical music arranger to present another interpretation of the Dead’s catalog, famous for never being performed the same way, this time with an ensemble that mostly plays what it says on the sheet music—the 80-piece National Symphony Orchestra.
In a 2022 interview with NPR, Weir explained the reasons for this collaboration and, in doing so, offered a possible explanation for why the band's music has remained popular for so long: "These songs are... living beings and they are visitors from some other world - another dimension or whatever you want to call it - who come through the artists to visit this world, look around it and tell their stories. I don't know exactly how it works, but I know it's real."
Vir's work to preserve and nurture the Dead's legacy has been rewarded by younger generations of Deadheads, the band's loyal followers, who have gone on tour after tour, often following the band from city to city, just as their parents and grandparents did during the 1960s, 70s, 80s and 90s.
In an interview with Rolling Stone in March 2025, Weir shared thoughts on his legacy, as well as death and dying, that echoed the Eastern philosophies popular at the time the Grateful Dead emerged from the peace and love hippie movement in San Francisco. "I'll say this: I look forward to death. I see death as the reward for a life well lived," he said.
