'An Unprecedented Discovery': The Prepared Piano Revelations of Pianist Jessica Williams

While browsing the jazz section at a vinyl outlet a few years ago, producer Kye Potter discovered a battered tape by pianist and composer Jessica Williams. It seemed like the quintessential DIY release. "The labels had come off the tape," he says. "It was personally duplicated, with xeroxed liners, a dab of fluorescent marker to highlight the artwork, and put out on her own label, Ear Art."

Being a collector deeply fascinated by the U.S. experimental scene after John Cage, Potter was intrigued by a tape titled Prepared Piano. But it appeared atypical for Williams, who was primarily recognized for producing sparkling jazz in the direct lineage of Thelonious Monk and Errol Garner.

Although the west coast jazz circuit knew her as a musical experimenter – during her performances, she requested pianos lacking the lid to allow her to reach inside and pluck the strings – it was a facet that seldom found its way on her records.

"I had never encountered anything like it," Potter states regarding the tape. Consequently, he contacted Williams to inquire if further recordings had been made. She provided four recordings of altered piano from the 1980s – two concert recordings, two recorded in a studio. Even though she had stepped away from public performance years earlier, she also included some contemporary pieces. "She sent me approximately 15 or 16 synth tapes – complete albums," Potter explains.

A Legacy Release: Blue Abstraction

Potter worked with Williams throughout the pandemic to put together Blue Abstraction, an album of modified piano compositions that was published in late 2025. However, Williams died in 2022, midway through the project. She was 73. "She was facing health and money problems," Potter reveals. Williams had been open regarding her struggles after spinal surgery in 2012, which ended her ability to tour, and a cancer diagnosis in 2017. "Yet I feel her personality, strength, self-confidence and the peace she found through meditative practices all were evident in conversation."

In her subsequent synthesizer-driven, rhythm-based releases such as Blood Music (2008) – explicitly categorized "NOT JAZZ" – and the two Virtual Miles releases (2006 and 2007), you hear a artist attempting to escape tradition. Blue Abstraction, with its curiously transformed piano echoes, demonstrates that that impulse reached back decades. Instead of a consistent piano sound, the piano creates many different sonic evocations: what could be hammered dulcimers, gamelan, far-off chimes, animals rattling around cages, and small devices coughing to start. It possesses a powerfully immediate energy, with massive roars dissolving into biting, staccato riffs.

Artistic Recognition

Tortoise’s Jeff Parker says he is a fan of this "beautiful, varied, investigative and subtle" record. Jessika Kenney, who has collaborated with Sarah Davachi and Sunn O))), heard Williams play while studying in Seattle in the 1990s, and was attracted to the power of her music, but had scant knowledge of her otherworldly prepared piano until this release. Not long after attending Williams live, she traveled to Indonesia, pursuing "surrealism in the improvisational vocals of the Javanese gamelan," she says. "Currently, that feels completely natural as a relationship with her. I only wish it was understood by me then."

Technical Precursors

Williams’ prepared sounds have historical forerunners: consider John Cage’s prepared pianos, or the innovative methods of idiosyncratic composer Henry Cowell. What’s striking is how successfully she fuses these innovative timbres with her own soulful language at the keyboard. Her musical speech rarely departs from that which she cultivated in a body of work extending to more than 80 albums, meaning the new trippily tinted sounds are powered by the bubbling vitality of an artist in complete command. That's thrilling stuff.

A Lifelong Experimenter

Williams had always experimented with the piano. "When I played, I visualized colors," she noted in an interview. She obtained her first vertical piano in 1954. Through her online journal, she told the story of her first "taking apart" – "something I repeated for all pianos," she wrote: Williams detached a panel from beneath the piano’s keyboard, and placed it on the floor beside her stool. "Requiring percussion, my left foot acted as the hi-hat," she stated.

Initially, Williams studied classical piano at the Peabody Conservatory. Youthful exposures with the standard canon led her to Rachmaninov; she brought his famous Prelude in C minor to her piano teacher, who chastised her for embellishing a section. However, he detected her potential: the following week, he brought her Dave Brubeck to play. She figured out his Take Five within a week.

Jazz World Disillusionment

Subsequently, Brubeck refer to Williams "one of the greatest pianists I have ever heard," and McCoy Tyner was just as awed. Williams’ 2004 Grammy-nominated album Live at Yoshi’s, Vol 1, exhibits her deep knowledge of jazz history, plus her trademark playful pianistic wit. However, despite her dedicated efforts to learn about the genre – first, to the hipper sounds of Coltrane, Miles and Dolphy, before tracing a path back to Monk and Garner to Fats Waller and James P Johnson – she quickly became disillusioned with the jazz world.

After moving from Philadelphia to San Francisco, Williams encountered the great Mary Lou Williams. Inspired by the senior musician's advice ("Don’t ever let anyone stop you"), she emerged as a outspoken, vocal critic of her scene: of the poor compensation, the jazz "old boys' network," the "scene networking" – namely smoking and drinking as the main method of getting gigs – and of a commercial business profiting from the work of struggling artists.

"I remain constantly disappointed at the nature of the ‘jazz world’ and its inability to organise, communicate and stand up for a set, any set, of essential beliefs," she stated in the album notes to her 2008 release Deep Monk. In the same vein, the writing on her blog was eclectic, unflinching, decidedly ideological and feminist, though she seldom talked about her experiences as a trans individual. A commentator observed: "To add to the sexism … that chased her from her chosen artistic field for a period, imagine what kind of cruel nonsense she must have endured as a trans woman in the jazz scene of the early 80s."

Forging an Autonomous Career

The artist's trajectory evolved into self-sufficiency. After time in the bustling Bay Area scene, she relocated to smaller cities such as Sacramento and Santa Cruz, settling in Portland in 1991, and later moving smaller still, to Yakima, Washington State, in the 2010s. Williams recognized early the huge potential of the internet
