Grateful Dead Co-Founding Bassist Phil Lesh Has Died

Founding Grateful Dead bassist Phil Lesh has died. He was 84.

No cause of death was immediately given, though Lesh had revealed a bout with bladder cancer in 2015. “He was surrounded by his family and full of love,” according to an official statement. “Phil brought immense joy to everyone around him and leaves behind a legacy of music and love. We request that you respect the Lesh family’s privacy at this time.”

A classically trained trumpeter, Lesh switched to bass at the late Jerry Garcia ‘s request after joining a fledgling Bay Area band called the Warlocks. He’d met Garcia in passing a couple of times, and they hit it off. The Warlocks were soon rechristened as the Grateful Dead, then took over as the house band during Ken Kesey’s legendary Acid Tests.

Soon, Lesh was co-writing some of their best-known songs, including “Truckin'” and “Box of Rain.” He also initially provided tenor backing vocals, as heard on their turn of the ’70s classics Workingman’s Dead and American Beauty.

The Grateful Dead toured and recorded from 1965 until Garcia’s death in 1995, a loss that deeply impacted Lesh. “Jerry was the hub,” he later told Rolling Stone. “We were the spokes. And the music was the tread on the wheel.”

Lesh wrote the only memoir from a band member to date, with 2005’s Searching for the Sound: My Life With the Grateful Dead. He and his wife Jill opened a restaurant and live music venue called Terrapin Crossroads in 2012 in San Rafael, California.

He continued to perform long after his time with the Dead was over. The Berkeley native fronted Phil Lesh and Friends, performed in Further and the Other Ones with former bandmates, and continued to appear with his family band into 2024. Lesh took part in the 2015’s Fare Thee Well shows in Chicago to celebrate the Grateful Dead’s 50th anniversary, appearing with Trey Anastasio of Phish. He would also occasionally sit in with the house band at Terrapin Crossroads, which featured his sons.

“I would have to say that music and performing are as essential as food and drink to me, but even more so as I get older,” he told Mercury News earlier this year. “While it can sometimes be more of a challenge physically than it was when I was a young whippersnapper, I’ve found that age brings wisdom, and with that comes musical experience and knowledge that I didn’t have when I was younger.”

The Grateful Dead were named 2025 MusiCares Persons of the Year earlier this week. Lesh and fellow surviving original members Mickey Hart, Bill Kreutzmann and Bobby Weir were set to be honored at the organization’s benefit gala during Grammy Week. The band’s original lineup was included the late Ron “Pigpen” McKernan.

Lesh missed an August headlining set at Sunday Daydream Vol. 4 in San Rafael, California, after testing positive for COVID.
