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

Flipping through the jazz section at a vinyl outlet a few years ago, collector Kye Potter came across a battered tape by pianist and composer Jessica Williams. It appeared like the ultimate homemade project. "The labels had detached from the tape," he says. "It was home-dubbed, with printed inserts, a dab of fluorescent marker to accentuate the artwork, and put out on her own label, Ear Art."

Being a collector particularly interested in the American musical avant garde following John Cage, Potter was intrigued by a tape titled Prepared Piano. Yet it seemed atypical for Williams, who was most famous for producing lively jazz in the straight-ahead tradition of Thelonious Monk and Errol Garner.

If the West Coast scene knew her as a creative innovator – during her performances, she asked for pianos with the top removed to make it easier to access the interior and strum the strings – it was a aspect that infrequently appeared on her releases.

"I'd never heard anything like it," Potter states regarding the tape. Consequently, he contacted Williams to inquire if further recordings had been made. She sent back four recordings of prepared piano from the mid-80s – two live, two recorded in a studio. Although she had long since retired years earlier, she also shared some contemporary pieces. "She sent me approximately 15 or 16 electronic music cassettes – full releases," Potter explains.

A Legacy Release: Blue Abstraction

Potter partnered with Williams throughout the pandemic to compile Blue Abstraction, an album of prepared piano pieces that was published in late 2025. Tragically, Williams passed away in 2022, part way through the project. She was 73. "She was struggling physically and financially," 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. "However, I believe her personality, strength, self-confidence and the calmness she found through having a spiritual practice all were evident in conversation."

Within her more recent electronic, groove-focused releases such as Blood Music (2008) – boldly labeled "NOT JAZZ" – and the two Virtual Miles releases (2006 and 2007), you hear a artist attempting to transcend convention. Blue Abstraction, with its fascinatingly modified piano resonances, demonstrates that that drive extended back decades. In place of a uniform piano sound, the piano creates many different sonic evocations: what could be hammered dulcimers, Indonesian percussion, remote carillons, animals rattling around cages, and tiny engines spluttering into life. It possesses a incredibly pressing energy, with monumental roars giving way to biting, staccato riffs.

Listener Praise

Tortoise’s Jeff Parker states he is a fan of this "gorgeous, diverse, exploratory and nuanced" record. Composer Jessika Kenney, who has worked with Sarah Davachi and Sunn O))), saw Williams play while being a student in Seattle in the 1990s, and was drawn to the intensity of her music, but knew little of her surreal-sounding prepared piano prior to this release. Shortly after witnessing Williams live, she traveled to Indonesia, in search of "the dreamlike quality of improvised singing of the Javanese gamelan," she recalls. "Now that seems completely natural as a relationship with her. I only wish it was understood by me then."

Artistic Forebears

Her altered piano techniques have technical precursors: consider John Cage’s altered keyboards, or the innovative methods of U.S. maverick Henry Cowell. What is remarkable is how successfully she fuses these innovative timbres with her own jazzy lexicon at the keyboard. The stylistic approach hardly ever strays from that which she developed in a discography spanning more than 80 albums, meaning the new hallucinogenically hued sounds are powered by the fizzy energy of an artist in total mastery. This is thrilling stuff.

A Constant Innovator

Williams had always tinkered with the piano. "I hit the notes, and I saw colours," she reportedly said. She obtained her first vertical piano in 1954. In her writings, she recounted the tale 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 next to her stool. "Seeking rhythm, my left foot turned into the hi-hat pedal," she explained.

Initially, Williams learned classical piano at the Peabody Conservatory. Initial experiences with the classical repertoire led her to Rachmaninov; she took his famous Prelude in C minor to her piano teacher, who reprimanded her for improvising a section. Yet he recognized her potential: the next week, he introduced her to Dave Brubeck to play. She mastered 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, exhibits her deep knowledge of jazz history, plus her signature clever pianistic wit. Nevertheless, despite her long journeys to study the genre – first, to the more modern styles of Coltrane, Miles and Dolphy, before moving backwards to Monk and Garner to Fats Waller and James P Johnson – she rapidly felt disillusioned with the jazz world.

After moving from Philadelphia to San Francisco, Williams was introduced to the great Mary Lou Williams. Inspired by the elder pianist's advice ("Don’t ever let anyone stop you"), she turned into a outspoken, vocal critic of her scene: of the low wages, the jazz "old boys' network," the "jazz hang" – namely smoking and drinking as the key way of securing work – and of a commercial business riding on the coattails of struggling artists.

"I am continually disappointed at the reality of the ‘jazz world’ and its inability 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, unflinching, openly political and feminist, though she infrequently addressed her experiences as a trans individual. As one critic noted: "To add to the sexism … that drove her from her preferred musical arena for a period, imagine what kind of inhumane bullshit she must have suffered as a trans woman in the jazz scene of the early 80s."

The Path to Self-Sufficiency

The artist's trajectory arced towards self-sufficiency. Subsequent to a stint in the active Bay Area scene, she lived in 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 understood from the beginning the huge potential of the internet
