San Jose City Hall goes psychedelic to honor Grateful Dead concert Today Us News


The plaza behind San Jose City Hall was filled with Deadheads and DJs on Thursday night, as the city distinctively celebrated its historic connection to the Grateful Dead by illuminating City Hall in light show of swirling colors, with the legendary band’s music ringing out in the courtyard.

The festivities marked the 60th anniversary of a momentous night when the band, just having changed its name from the Warlocks, played an LSD-fueled “acid test” at a house on South Fifth Street on Dec. 4, 1965. In the intervening 60 years, the house was moved to make way for City Hall, but a plaque commemorating the spot was unveiled Thursday night. Featuring the band’s famous “Steal Your Face” logo, the plaque will be permanently affixed to the wing’s south wall.

“There’s no acid test tonight, but I’m thinking there might be a little acid reflux, looking around,” emcee Kim Vestal, a longtime DJ now doing traffic for KCBS, told the well-seasoned crowd.

The ceremony leading up to the plaque’s reveal included remarks from the two guys who have been spearheading this effort for years on behalf of nonprofit San Jose Rocks: founder Dan Orloff and former Mercury News sports columnist Mark Purdy. You think it’s hard work trying to get a remodeling permit? Try getting a plaque on city hall commemorating an event where people took LSD (which, as was pointed out several times Thursday, was perfectly legal at the time).

There were a couple of surprise guests, too. Ira Meltzer was a San Jose State student who lived at the house and talked about the wild night, which had Jerry Garcia, Bob Weir, Phil Lesh, Ron “Pigpen” McKernan and Bill Kreutzmann providing the music and Ken Kesey and his Merry Pranksters passing out the LSD-laced sugar cubes.

Another guest speaker was Trixie Garcia, the daughter of Jerry Garcia and Carolyn “Mountain Girl” Garcia. She was born nearly a decade after the night in question — both her parents were there — but said she thought it was wonderful that San Jose commemorated the moment.

“The ’60s changed the world, and what was started here in the Bay Area continues to lead the world and progressive thought and a more mindful way to exist,” she said.

While passerbys took pictures and marveled at the light show projected on City Hall, visitors inside the Janet Gray Hayes Rotunda got to view a collection of Grateful Dead posters owned by collector Bill Guardino and get an up-close look at an original hand-drawn poster promoting the acid test The poster recently sold at auction for $37,500. It also led Orloff and Purdy down a research rabbit hole only to discover that the historic house  at 38 S. Fifth St. hadn’t been lost in a fire — as previously thought — but was repaired and moved to North Fourth Street, just blocks away.
