What happened
Bob Weir, a founding member, vocalist and distinctive rhythm guitarist of the Grateful Dead, has died at the age of 78, his family announced. The statement said he had previously defeated cancer but ultimately succumbed to underlying lung issues and that he passed peacefully surrounded by loved ones; a specific date of death was not immediately available. Weir’s career spanned six decades: he co‑founded the band with Jerry Garcia after meeting him in the mid‑1960s, contributed key songs and arrangements to landmark 1970 albums Workingman’s Dead and American Beauty, and wrote Dead standards that included tracks from his solo record Ace. He performed in numerous side projects over the years—Kingfish, Bobby and the Midnites, RatDog, Dead & Company and Bobby Weir & Wolf Bros among them—and continued touring into the 2020s. His final onstage appearances were a three‑night Golden Gate Park run marking the band’s 60th anniversary; the family said he had been diagnosed in July and began treatment weeks before those shows.
