PACT: Psychedelic Arts and Culture Trust

GRASS VALLEY, CA. The Psychedelic Arts and Culture Trust (PACT) celebrates the sixtieth anniversary of the Grateful Dead with 60 Years of the Grateful Dead, a landmark retrospective honoring the original art and imagery that shaped the band’s identity across six decades of music, culture and myth.

Curated by Brian Chambers, the exhibition gathers many of the original works created for the Dead’s most iconic posters and album covers. Featured artists include Rick Griffin, Stanley Mouse, Alton Kelley, Victor Moscoso, Wes Wilson, Bill Walker, Owsley “Bear” Stanley and others whose work helped define the psychedelic era.

—————————

Highlights include

Rick Griffin Originals
Historic illustrations, preliminary sketches, paintings and artifacts, including the original pen and ink Hawaiian Aoxomoxoa drawing considered one of the finest works of psychedelic typography, his acrylic circus paintings for Without a Net, the original Europe 90 tour poster and his first major work, the 1967 “Pow-Wow” Human Be-In poster.

Bill Walker’s Anthem of the Sun
A massive, vibrant mandala of color and rhythm created for the band’s second album. Walker continued refining the piece for decades after its use on the cover, capturing the spirit of the late sixties and the creative impact of LSD on art.

Historic Acid Test posters
Designed by Paul Foster and hand colored by Owsley “Bear” Stanley, including the first public use of the name “Grateful Dead” after the band’s early Warlocks era, and the only known signed copy of Bear’s 1966 Trouper’s Club poster.

A Original Skeleton Amidst Roses
Created by Victorian artist Edmund J. Sullivan in 1900 and later published in the 1913 edition of The Rubaiyat of Omar Khayyam, this original A Skeleton Amid Roses illustration was adapted by Mouse and Kelley for the Avalon Ballroom in 1966 and for the 1971 Skull and Roses album. This marks the first time the original drawing has been exhibited in a Grateful Dead show.

Pioneers and Modern Masters
Limited edition posters and original works by contemporary poster artists AJ Masthay and Zoltron, who carry forward the counterculture tradition.

Exclusive New Grateful Dead merch

A rock concert style merchandise booth will offer brand new, officially licensed and extremely limited edition Grateful Dead gear designed and curated by Zoltron.

60 Years of the Grateful Dead opens Saturday, December 6, 2025, two days after the anniversary of the band’s founding, and runs through June 1, 2026. 

Gallery is open Monday-Friday from 10am-5pm.

Tie-dye has come a long way since the turned-on and tuned-in 1960s. Harry Hart’s intricate and subtle patterns take the ancient art to a new level of complexity and scale in an amazing exhibit of cutting-edge art at the Chambers Project. 

Pioneering owner and curator Brian Chambers has succeeded in establishing the Chambers Project as the heart and soul of an astonishing flood of creative work created by historic and contemporary psychedelic artists. He promises his internationally famed gallery will be covered in “…head to toe tie-dye. Tie-dye is a favorite medium at The Chambers Project and over the years we have done countless limited-edition tie-dyed shirts. The response has always been very strong. With Harry and I sharing the same Southern roots and love of Grateful Dead culture this is a prime opportunity to elevate the medium to a higher level. ‘Dead to the Core’ is our first all tie-dyed show, and it’s definitely something I’m looking forward to exploring more in the future.”

The show is a refreshing acknowledgement of the cultural significance of resistance dyeing, which has ancient roots in Asian and African cultures, and is an outsider product of contemporary bohemian culture. Hart said, “I find myself gravitating to shibori, an ancient Japanese technique of binding fabric and submerging it in indigo vats. I’ve blended the shibori technique with approaches other people take, and combining the two gives me a look that stands out… I’ve taken a long time to fight the current and develop my own sense of style.” To achieve new levels of sophistication and subtlety he uses different weights of fishing line, artificial sinews, and bowstrings, lending to his work intricate complexity. Hart said tying and dyeing fabric is a unique art form, because unlike painting or sculpture which allow the artist to constantly make changes as they work, he never knows exactly what the finished piece will look like for days as he works toward completing a major piece. “It’s such an interesting thing, to not see anything you’re doing until the very end result,” he said. His skill determines the outcome, but there is always a degree of chance in the work.

Hart is sharing the opening night celebration of his show by presenting collaborative works from internationally acclaimed psychedelic artists Colin Prahl and Damon Soule, who will collaborate with Hart, and the innovative Scott Youngberg, who has brought figurative representation to resistance dyeing techniques. Artists Prahl and Soule will be painting over some of Hart’s pre-prepared works stretched on barred wooden frames like canvases, creating unprecedented collaborative mixed media images of pigment and dye. 

“Collaboration has always been the foundation of The Chambers Project,” said Chambers, who supports the Furtherrr psychedelic art collective in their production of huge and extraordinary psychedelic paintings, created during live performances at festivals and at his gallery openings. Enthusiastic about the idea, Hart added, “I’m excited to bring all sorts of mixed media collaborations under one roof.” 

At the opening, some of his largest dyes will be lit under LED lights smoothly shifting through the color spectrum, giving them an unusual sense of life and movement. “It’s going to give people a feeling I don’t think has been captured before,” he said, “I’m definitely not the first person to come across using RGB LED’s to transition pigments from one color spectrum to the other, but there’s innovation in the way I’ve created pieces of art with intention for light.”

Chambers sees Hart’s exhibit as a lead-in to the spectacular exhibit of art and artifacts of the Grateful Dead he is opening in December. The band frequently performed live sets in front of tie-dyed backdrops created by Courtenay Pollock. Chambers commented, “While tie-dye has been around far longer than the Grateful Dead, I feel it was the band’s culture and community that put the countercultural and underground spotlight on it. Harry Hart’s show felt like a proper way to lead into our ‘60 Years of the Grateful Dead’ retrospective exhibit in December, when we will further examine many more of the creative fractals that exploded through the culture of the Grateful Dead.”

Honoring his predecessor in pop-culture, Hart said, “Who knows what Courtenay would have been doing with the accessibility to the things that I have. I think that a lot of the difference is just the time and the place that we are. I have had massive inspiration from people like him.”

ARTIST BIO

Harry Hart is a Nashville-based dye artist known for his large-scale psychedelic mindscapes. Raised in Memphis, Tennessee, in a family of musicians, Harry’s creative journey has been shaped by both music and nature. In 2017, he and his wife, Hannah, along with their dog, Toni, moved to a peaceful home outside of Nashville, where they’ve embraced the serenity of the countryside.

Though Harry has been inspired by the music of the Grateful Dead and Widespread Panic from a very young age, his dive into dye art began unexpectedly in 2020. Within a week of dyeing his first shirt , he began dreaming about the colors and patterns that would define his work. This rapid immersion into the craft sparked a journey that has taken off at lightning speed. What began as a personal exploration soon blossomed into a full-time passion, gaining traction and popularity in the psychedelic art community.

Harry’s art is influenced by the geometric patterns he finds in nature, from the spirals of seashells to the fractals in plant life. His connection to the natural world, combined with a deep love for time spent outdoors, provides endless inspiration for his vibrant, psychedelic designs. His momentum has only grown, with his pieces now displayed at every Widespread Panic show so since February 2025 — four works in their collection—a testament to his growing recognition in the scene.

For Harry, there’s no looking back. He’s found his place in the vibrant tapestry of psychedelic art, and the journey is just beginning.

SAM GRISMAN PROJECT

BENEFIT CONCERT FOR UNCLE JAY

APRIL 7, 2024

2PM-8PM

627 E Main St,
Grass Valley, CA 95945

Join us on Sunday April 7th at The Chambers Project for a very special concert to support our friend and fellow Nevada County resident, Uncle Jay.

SOME WORDS FROM SAM GRISMAN,

I am honored to be bringing some of my closest friends and most favorite musicians to the incredible psychedelic art gallery “The Chambers Project” in Grass Valley, CA on Sunday, April 7th for a day of art and music to benefit my dear Uncle Jay, an absolute pillar of that community.

Uncle Jay and Aunt Mary were there the day I was born and they are some of the kindest people and greatest champions of Dawg music on planet earth. They have known my dad since they came backstage at the Great American Music Hall in 1976 with a killer joint, and they’ve been dear friends ever since. Jay is a masterful cannabis cultivator, an incredibly brilliant renaissance man, and a great mandolin picker!

Many a David Grisman Quintet show and recording session has been fueled by Jay’s incredible herb, and Jay and Mary have made friends with legions of folks around the country through their passion for music and their supremely high caliber artisanship. Lots of amazing musicians have enjoyed Jay’s weed over the years including the likes of Jerry Garcia, John Hartford, Willie Nelson, Tim O’Brien, Jerry Douglas, and Sam Bush. I even once handed I joint I rolled of Jay’s weed directly to Merle Haggard, and I know he loved it!

Unfortunately, Uncle Jay has a battle with cancer ahead of him, and to spread awareness and raise some funds for his medical expenses we’ll be having a day of music and art in his honor. I’ll have the great @chrishollywoodenglish , @domles , @roywilliamsmusic , and myself as the house band, and we’ll be joined by a bunch of Jay’s musical supporters, including DGQ Alumnus Joe Craven, and his Daughter Hattie, fellow Dawg alum Matt Eakle, the legendary “Banana” of the Youngbloods, and more friends to come! There will also be a silent auction, some merchandise, and some special surprises, and all of the proceeds will go directly to benefit Jay and Mary as they kick cancers ass and launch the greatest YouTube channel on the planet!

Tickets are on sale now, thanks for your support.
