'An Unprecedented Discovery': The Altered Instrument Discoveries of Jazz Star Jessica Williams

While browsing the jazz section at a neighborhood shop a few years ago, producer Kye Potter discovered a worn cassette by musician Jessica Williams. It appeared like the classic independent effort. "The labels had detached from the tape," he says. "It was personally duplicated, with xeroxed liners, a little bit of highlighter to emphasize the artwork, and issued on her own label, Ear Art."

As a collector deeply fascinated by the American musical avant garde following John Cage, Potter was captivated by a tape titled Prepared Piano. Yet it seemed out of character for Williams, who was best known for creating vibrant jazz in the direct lineage of Thelonious Monk and Errol Garner.

Although the California jazz community knew her as a creative innovator – at her live shows, she asked for pianos lacking the lid to make it easier to access the interior and pluck the strings – it was a aspect that infrequently appeared on her albums.

"I'd never heard anything like it," Potter remarks regarding the tape. Consequently, he contacted Williams to ask if additional recordings existed. She sent back four recordings of altered piano from the 1980s – two live, two made in the studio. Although she had long since retired some time before, she also shared some newer material. "She sent me around 15 or 16 synth tapes – full releases," says Potter.

A Posthumous Project: Blue Abstraction

Potter partnered with Williams during the Covid pandemic to assemble Blue Abstraction, an album of modified piano compositions that was issued in late 2025. However, Williams died in 2022, during the project. Her age was seventy-three. "She was facing health and money problems," Potter says. Williams had been open regarding her hardships after spinal surgery in 2012, which meant she could no longer tour, and a diagnosis of cancer in 2017. "However, I believe her character, fortitude, assurance and the serenity she found through having a spiritual practice all were evident in conversation."

In her subsequent electronic, groove-focused releases such as Blood Music (2008) – defiantly tagged "NOT JAZZ" – and the two Virtual Miles releases (2006 and 2007), you hear a musician seeking to transcend tradition. Blue Abstraction, with its curiously transformed piano resonances, shows that that impulse stretched back decades. In place of a consistent piano sound, the instrument creates numerous distinct sonic evocations: what could be hammered dulcimers, gamelan, remote carillons, animals rattling around cages, and little machines sparking to life. It possesses a tremendously urgent energy, with massive roars giving way to biting, staccato riffs.

Critical Acclaim

Musician Jeff Parker says he is a fan of this "gorgeous, diverse, exploratory and nuanced" record. Vocalist Jessika Kenney, who has partnered 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 prior to this release. Shortly after attending Williams live, she traveled to Indonesia, pursuing "the abstract vocalizations of the Javanese gamelan," she recalls. "Now that seems completely natural as a connection with her. I only wish it was familiar to me then."

Artistic Forebears

These modified tones have technical precursors: reflect on John Cage’s prepared pianos, or the radical techniques of American eccentric Henry Cowell. The notable aspect is how masterfully she fuses these innovative timbres with her own soulful language at the keyboard. Her musical speech scarcely deviates from that which she developed in a body of work extending to more than 80 albums, ensuring that the new trippily tinted sounds are powered by the bubbling vitality of an artist in full control. That's exhilarating material.

A Constant Innovator

Williams had always tinkered with the piano. "Striking keys produced hues in my mind," she noted in an interview. She was given her first vertical piano in 1954. On her blog, she recounted the tale of her first "disassembling" – "as I’ve done for all pianos," she noted: Williams removed a panel from below the piano’s keyboard, and put it on the floor alongside her stool. "Seeking rhythm, my left foot turned into the hi-hat pedal," she wrote.

Early on, Williams trained in classical piano at the Peabody Conservatory. Early encounters with the traditional pieces led her to Rachmaninov; she took his famous Prelude in C minor to her piano teacher, who reprimanded her for embellishing a section. Yet he recognized her potential: the following week, he brought her Dave Brubeck to play. She mastered his Take Five within a week.

Jazz World Disillusionment

Brubeck would later describe 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, shows her deep immersion in jazz history, plus her characteristic whimsical pianistic wit. However, despite her dedicated efforts to educate herself the genre – first, to the hipper sounds of Coltrane, Miles and Dolphy, before working her way back to Monk and Garner to Fats Waller and James P Johnson – she soon grew disenchanted with the jazz world.

After moving from Philadelphia to San Francisco, Williams encountered the great Mary Lou Williams. Encouraged by the elder pianist's advice ("Don’t ever let anyone stop you"), she turned into a forceful, open critic of her scene: of the poor compensation, the jazz "boys’ club," the "typical jazz socializing" – namely smoking and drinking as the key way of securing work – and of a commercial business benefiting from the efforts of struggling artists.

"I am repeatedly disappointed at the nature of the ‘jazz world’ and its failure to unite, discuss, and defend 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 broad in scope, direct, openly political and feminist, though she infrequently addressed her experiences as a trans woman. A commentator observed: "To add to the sexism … that drove her from her chosen artistic field for a period, imagine what kind of cruel nonsense she must have suffered as a trans woman in the jazz scene of the early 80s."

Forging an Autonomous Career

Williams’ career arced towards self-sufficiency. Subsequent to a stint in the bustling Bay Area scene, she relocated to smaller cities such as Sacramento and Santa Cruz, moving to Portland in 1991, and later going to a more remote location, to Yakima, Washington State, in the 2010s. Williams saw early on the huge potential of the internet
