Borderline Visible

A new collection of writings by the composer and mathematician Spencer Gerhardt, considering among other topics the rich points of contact between minimalist musical aesthetics and intuitionistic mathematics.

Noted composer and mathematician Spencer Gerhardt presents Ticking Stripe, a groundbreaking collection of essays linking notions of continuity and construction across the boundaries of math, art, music and philosophy. Gerhardt offers new, and deeply informed interpretations of the 1960s New York avant-garde, viewed through the lens of trailblazing artists such as La Monte Young, Marian Zazeela, Catherine Christer Hennix, Henry Flynt and Tony Conrad.

Ticking Stripe pairs the spirit of L. E. J. Brouwer—a mathematician who brilliantly, and controversially, sought to reconstruct the continuum in his own philosophical terms called intuitionism—with the ambitions of pioneering minimalists who combined continued constructions, idealized processes of introspection, and conceptual world-building with a host of philosophical, scientific, and spiritual concerns. Informed by his own work as a professional mathematician and composer, Gerhardt explores the depths of these disparate traditions, finding unlikely areas of commonality. Spanning over two decades, these essays feature rich historical explorations of minimalist music, writing on contemporary art, and work in logic and algebraic groups, all approached with rare clarity and technical aplomb.

Spencer Gerhardt is a composer and mathematician. His music engages constructive, introspective and romantic traditions. Gerhardt has written solo piano music, piano based songs, and works of minimalism. He studied raga with La Monte Young and Marian Zazeela, piano performance with Sung-Hwa Park, and has collaborated with artists such as Thomas Ankersmit and Charles Curtis.

The republication in print form of the poems of Art Ensemble of Chicago's founding member breathes new life into a forgotten document of the Black Arts Movement.

In 1977, Art Ensemble of Chicago Publishing Co. published Jarman's Black Case Volume I and II: Return From Exile, a collection of writing conceived across America and Europe between 1960 and 1975. Comprised largely of Jarman's flowing, fiery free verse—influenced by Amus Mor, Henry Dumas, Thulani Davis, and Amiri Baraka—the book also features a manifesto for “GREAT BLACK MUSIC,” notated songs, concert program notes, Jarman's photos, and impressions of a play by Muhal Richard Abrams, the founder of the Association for the Advancement of Creative Musicians of which Jarman was also an original member.

Jarman writes poetry of personal revolutionary intent, aimed at routing his audience's consciousness towards growth and communication. He speaks with compassionate urgency of the struggles of growing up on Chicago's South Side, of racist police brutality and profound urban alienation, and of the responsibility he feels as a creative artist to nurture beauty and community through the heliocentric music that he considers the healing force of the universe. A practicing Buddhist and proponent of Aikido since a 1958 awakening saved him from the traumatic mental isolation of his time dropped by the US army into southeast Asia, Jarman sings praise for the self-awareness realization possible through the martial arts.

With cosmic breath as its leitmotif, his poetry both encourages and embodies a complete relinquishing of ego. While some of the poems contained within Black Case have already been immortalized via performances on classic records by Jarman and Art Ensemble of Chicago, its republication in print form breathes new life into a forgotten document of the Black Arts Movement.

Livre d’images sans images by Mette Edvardsen & Iben Edvardsen borrows its title from a book by H.C. Andersen, also referred to as The Moon Chronicler. The book follows a conversation between a painter and the Moon, where the Moon describes to the painter what she sees on her journey around the world every evening, telling the painter to paint what she describes. “This conversation, as in the now obsolete meaning of the word (‘a place where one lives or dwells’), was the starting point for our work. Using the weather report as dramaturgy, (‘the moon did not show up every evening, sometimes a cloud came in between’), we have created and collected materials from our conversations in the form of recordings, text, voice, drawings, references, found images, loose connections, inspirations and imaginations, in the order they came to us. They are at the same time sources and traces, material and support for new imaginations or events to come.” The work consists of three different media: vinyl, paper and live performance. 

Mette Edvardsen is a choreographer and performer eager to explore the performing arts as a practice and situation, also in relation to other media such as books and writing. This work is in collaboration with her daughter, Iben Edvardsen.

Recorded live at Amsterdam's Oude Kerk during the 2024 Sonic Acts Festival, The Organ is the World's Greatest Synthesizer finds Charlemagne Palestine returning to the Staalplaat catalog after many years. Taking its title and cover from a drawing made by Palestine during the performance, the work expands his singular mythology of sound and spirit. Opening with resonating bells and falsetto overtones before surrendering to the vast sonic tides of the church organ, the 40-minute piece unfolds as an ecstatic continuum—tones intertwining, frequencies colliding, and space itself becoming an instrument. A testament to the living dialogue between artist, instrument, and place, this is Palestine at his most immersive and transcendent.

For over six decades, Charlemagne Palestine has been a pioneering composer, performer, and multimedia artist, celebrated for his ecstatic sonic explorations and ritualistic, metaphysical performances. Emerging from the cross-disciplinary New York art scene of the 1960s and '70s, he helped shape a heretical edge of minimalism alongside figures like Conrad, Riley, Niblock, and Glass. Trained as a Jewish cantor and later as the carillonneur at St. Thomas Church, Palestine cultivated a deep fascination with resonance and overtone—an obsession that evolved through his use of percussion, early synthesizers, and monumental piano works, influencing artists from John Cale to Nick Cave.

DUCTUS is the latest solo project by Paul Abbott, featuring 51 minutes of audio, across 12 tracks, and a 42 page booklet featuring new writing. DUCTUS was written and recorded in Edinburgh and Porto in 2019. 

DUCTUS presents a playful weave of collapsing time through a number of speculative elements and fictional characters. Abbott feels his way through learning drums, rhythm and writing as fleshy research technologies. DUCTUS is the latest stage in a process considering sound, the body, imagination, and language through music. This features as part of ongoing investigations using real and imaginary drums, synthetic sounds, performance and writing.
