'An Unprecedented Discovery': Those Altered Instrument Revelations of Pianist Jessica Williams

While browsing the jazz records at a local record store a few years ago, producer Kye Potter came across a well-used recording by American pianist Jessica Williams. It appeared like the classic independent effort. "The labels had come off the tape," he says. "It was personally duplicated, with xeroxed liners, a touch of highlighter to emphasize the artwork, and put out on her own label, Ear Art."

Being a collector particularly interested in the avant-garde movement following John Cage, Potter was intrigued by a tape titled Prepared Piano. But it appeared atypical for Williams, who was primarily recognized for creating vibrant jazz in the conventional style of Thelonious Monk and Errol Garner.

While the west coast jazz circuit knew her as a sonic explorer – at her live shows, she asked for pianos with the top removed to facilitate to reach inside and pluck the strings – it was a aspect that infrequently appeared on her records.

"It was my first time hearing anything like it," Potter states regarding the tape. Consequently, he contacted Williams to see if further recordings were available. She provided four recordings of prepared piano from the 1980s – two live, two made in the studio. Even though she had stepped away from public performance some time before, she also included some newer material. "She sent me around 15 or 16 synthesizer recordings – entire projects," Potter recounts.

A Legacy Release: Blue Abstraction

Potter collaborated with Williams throughout the pandemic to put together Blue Abstraction, an album of altered piano works that was published in late 2025. However, Williams died in 2022, during the project. Her age was seventy-three. "She was dealing with physical and economic challenges," Potter says. Williams had been open regarding her difficulties after spinal surgery in 2012, which prevented her from tour, and a diagnosis of cancer in 2017. "However, I believe her personality, strength, self-confidence and the calmness she found through having a spiritual practice all came out in conversation."

In later synthesizer-driven, rhythm-based releases such as Blood Music (2008) – defiantly tagged "NOT JAZZ" – and the two Virtual Miles releases (2006 and 2007), you hear a artist trying to break free of expectation. Blue Abstraction, with its fascinatingly modified piano reverberations, shows that that drive reached back decades. Instead of a homogenous piano sound, the piano creates numerous distinct sonic evocations: what could be cimbaloms, gamelan, far-off chimes, animals rattling around cages, and tiny engines spluttering into life. It possesses a tremendously urgent energy, with colossal bellows dissolving into snarling, highly punctuated riffs.

Artistic Recognition

Musician Jeff Parker says he is a fan of this "gorgeous, diverse, exploratory and nuanced" record. Composer Jessika Kenney, who has collaborated with Sarah Davachi and Sunn O))), saw Williams play while studying in Seattle in the 1990s, and was captivated by the force of her music, but had scant knowledge of her surreal-sounding prepared piano until this release. Not long after attending Williams live, she traveled to Indonesia, seeking "the dreamlike quality of improvised singing of the Javanese gamelan," she recalls. "Today, that appears completely natural as a relationship with her. I only wish it was understood by me then."

Technical Precursors

Her altered piano techniques have historical forerunners: reflect on John Cage’s modified instruments, or the radical techniques of American eccentric Henry Cowell. What is remarkable is how successfully she blends these innovative timbres with her own soulful language at the keyboard. The stylistic approach scarcely deviates from that which she cultivated in a body of work stretching to more than 80 albums, so that the new hallucinogenically hued sounds are driven by the effervescent force of an performer in full control. That's electrifying music.

A Constant Innovator

Williams consistently tinkered with the piano. "When I played, I visualized colors," she once explained. She received her first upright piano in 1954. On her blog, she shared the anecdote of her first "taking apart" – "something I repeated for all pianos," she noted: Williams removed a panel from under the piano’s keyboard, and put it on the floor beside her stool. "Requiring percussion, my left foot acted as the hi-hat," she wrote.

Initially, Williams studied classical piano at the Peabody Conservatory. Early encounters with the classical repertoire led her to Rachmaninov; she brought his famous Prelude in C minor to her piano teacher, who reprimanded her for altering 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.

Industry Disappointment

Subsequently, Brubeck call Williams "among the finest pianists I have ever heard," and McCoy Tyner was just as awed. Williams’ 2004 Grammy-nominated album Live at Yoshi’s, Vol 1, displays her deep absorption in jazz history, plus her characteristic whimsical pianistic wit. However, despite her dedicated efforts to educate herself the genre – first, to the contemporary approaches of Coltrane, Miles and Dolphy, before working her way back to Monk and Garner to Fats Waller and James P Johnson – she rapidly felt disappointed with the jazz world.

After moving from Philadelphia to San Francisco, Williams met the great Mary Lou Williams. Buoyed up by the senior musician's advice ("Don’t ever let anyone stop you"), she became a forceful, open critic of her scene: of the low wages, the jazz "boys’ club," the "typical jazz socializing" – namely smoking and drinking as the key way of getting gigs – and of a profit-driven sector profiting from the work of financially strained musicians.

"I am continually disappointed at the truth of the ‘jazz world’ and its failure to unite, discuss, and defend a set, any set, of fundamental principles," she stated in the sleeve text to her 2008 release Deep Monk. Similarly, the writing on her blog was broad in scope, direct, expressly political and feminist, though she infrequently addressed her experiences as a trans woman. A commentator observed: "To add to the sexism … that chased her from her desired musical domain for a period, imagine what kind of cruel nonsense she must have faced as a trans woman in the jazz scene of the early 80s."

The Path to Self-Sufficiency

The artist's trajectory evolved into self-sufficiency. Subsequent to a stint in the bustling Bay Area scene, she lived in smaller cities such as Sacramento and Santa Cruz, settling in Portland in 1991, and later relocating to an even quieter place, to Yakima, Washington State, in the 2010s. Williams understood from the beginning the immense possibilities of the internet
