Legal archives and financial instruments are rarely the breeding ground for profound artistic creation, yet they sit at the heart of a landmark musical endeavor coming to London in late 2026. Atlantic Requiem, a sweeping 45-minute composition by British-Caribbean composer Dr. David Önasch, transforms chilling historical documents from the transatlantic slave trade into a monumental work for the London Symphony Orchestra (LSO) and the BBC Singers.
Commissioned by Dr. Errol Francis, director of the arts and heritage charity Culture&, the piece draws its textual and conceptual framework from historical insurance contracts housed within the archives of Lloyd’s of London. These records, meticulously digitized by Professor Alexandre White of Johns Hopkins University for the Underwriting Souls project, expose the chilling reality of how maritime insurers systematically quantified and traded human lives as "cargo."
Rather than relying purely on historical abstraction, Önasch has constructed a multi-layered, five-movement choral and orchestral landscape that confronts the chilling rationalization of slavery through the emotional depths of Western classical music, jazz, gospel, and spirituals. Conducted by Grammy Award-winner Anthony Parnther and featuring a stellar lineup of soloists—including soprano Brittany Renee, mezzo-soprano J’Nai Bridges, and tenor Orson Van Gay II—the work will receive its world premiere at LSO St Luke’s on Sunday, October 11, 2026. LSO Live will record the performance, cementing its place as a historical and cultural memorial.
Detailed Chronology
From Ledger to Libretto: Uncovering the Archives
The genesis of Atlantic Requiem lies in the opening of historical archives that shed light on corporate complicity in the transatlantic slave trade. Lloyd’s of London, one of the world’s oldest insurance markets, opened its historical records, exposing documents that reduced enslaved human beings to insurable commodities.
Professor Alexandre White’s work on the Underwriting Souls digital archive—funded by the Mellon Foundation via the "Black, Beyond Data" initiative—brought these grim transactions into the light. The chilling juxtaposition within these documents struck anyone who read them: the stark contrast between grand religious invocations and the bureaucratic dehumanization of human cargo. For instance, the infamous Lloyd’s Insurance Agreement for the slave ship Guipúzcoa famously begins with the invocation, "In the name of God, Amen…"
Commissioning the Artistic Response
Recognizing that numerical abstractions and historical facts fail to capture the visceral horror of systemic human commodification, Dr. Errol Francis of Culture& sought an artistic intervention. He approached David Önasch, a composer uniquely positioned by his transatlantic upbringing and dual heritage to interpret the material.
At the time of the commission, Önasch was already exploring cultural fusions through his arrangement of 20 Spirituals for Piano and his violin duo, Out of the Blue, which successfully integrated jazz, gospel, and classical idioms. The invitation to write a requiem provided a vast canvas to synthesize these musical worlds while addressing deep-seated historical trauma.
Structural Evolution of the Libretto
Önasch approached the libretto by placing the cold legalese of the insurance documents into direct conflict with traditional Catholic Requiem Mass texts (Requiem Aeternam, Kyrie Eleison, Dies Irae). Across five distinct movements, the text acts as a multi-voiced dialogue of commentary, corroboration, and critique:
- Movement I: Requiem in Records – Utilizes abridged, verbatim text from the Guipúzcoa insurance agreement juxtaposed with the Requiem Aeternam, slowly revealing that the divine prayers are offered for unnamed, commodified human beings.
- Movement II: Kyrie from the Depths – Travels across the Atlantic using a 1791 Grand Jury testimony from Cranston (sourced via the Newport Historical Society, Connecticut). It recounts the harrowing judicial record of a smallpox-infected enslaved woman who was bound, blindfolded, gagged, and thrown alive into the sea to prevent further financial loss for the shipowners.
- Movement III: Exodus Eschatologised – The emotional nadir of the work, structured as a ferocious Dies Irae. It contrasts biblical judgments against kidnapping and human trafficking (such as Exodus 21:16) with affirmations of beauty from the Song of Songs ("Dark am I, yet lovely…").
- Movements IV & V: Agnus Dei & Caeruleus Lux Perpetua (Perpetual Blue Light) – Shifts the tonal trajectory toward transcendence, incorporating Latin texts and visions from the Book of Revelation ("And I saw a new heaven and a new earth…"). Rather than ending in despair, the final movement looks toward a future of restored human dignity and racial harmony.
Supporting Context & Metrics
The Sonic Architecture of Segregation and Unity
To mirror the themes of division, displacement, and reconciliation, Önasch devised a rigorous compositional constraint based on the physical layout of the piano keyboard:
- The Pentatonic Constraint: The entire 45-minute score is constructed strictly using two five-note (pentatonic) groups—one representing the five black keys, and the other the seven white keys (restricted to five white notes). Notably, the notes F and B are entirely absent from the entire work.
- An Analogy for Race: This harmonic segregation serves as an acoustic metaphor for racial division and visible difference, while simultaneously demonstrating fundamental sameness, equality, and structural unity. The pentatonic groupings naturally bridge the gap between the pentatonic scales of blues, jazz, and gospel, and the open strings of an orchestra tuning up.
- Rhythmic and Orchestral Integration: "Swung" and "straight" rhythms are initially opposed before being combined. Similarly, instruments traditionally siloed into either "classical" or "jazz" categories follow a trajectory from conflict to profound reconciliation.
A Multilayered Acoustic World
The resulting soundworld is remarkably diverse. Formal Catholic chant meets rap and natural speech patterns. Intensely violent, dissonant ten-note orchestral chords sit alongside lush four-part choral harmonies.
Listeners are immersed in historical maritime soundscapes—evoking boatswain’s whistles and the Lloyd’s Lutine Bell—while structural rhythms draw influence from Igor Stravinsky, Béla Bartók, and György Ligeti, alongside the contemporary jazz-fusion grooves of Snarky Puppy, the neo-soul of Robert Glasper and Gretchen Parlato, and the heavy downbeats of Zulu warrior dances.
Official Statements
Reflecting on the psychological and biographical roots of the piece, composer Dr. David Önasch has articulated the deep personal stakes involved in its creation:
"As a person of mixed race, this piece had to connect to my own conundrum of identity, the questions of racial belonging which I have wrestled with all my conscious life, and the language of exclusion I have experienced from both sides. I’m not black enough… and at the same time not white enough. Do I float in the vacuum of everywhere and nowhere at once?"
Emphasizing the ultimate message of the Atlantic Requiem, Önasch noted:
"Racial devaluing in particular, because colour is such a visible characteristic of us all, is an especially pernicious perversion of precisely what ought to be celebrated: that the unifying racial glory of humanity consists so profoundly in the diversity of race present on this planet that to segregate is what reduces us to the subhuman not the other way round!"
Dr. Errol Francis, director of Culture&, underscored the necessity of artistic intervention when confronting historical atrocities:
The systemic undervaluing of human life encapsulated in historical insurance documents demands a depth of response that cold facts and figures cannot provide, requiring the profound emotional and cultural resonance that only music and the arts can deliver.
Future Outlook
The premiere of Atlantic Requiem on Sunday, October 11, 2026, at LSO St Luke’s marks a major milestone in contemporary classical music programming, bridging historical archival research with modern social commentary.
By capturing the live performances for LSO Live, the organizations involved aim to establish a permanent cultural artifact that memorializes the lives of enslaved Africans while honoring the enduring contributions of their descendants to transatlantic culture.
Looking forward, the creators hope the piece will serve as a vehicle for collective mourning, societal reflection, and a renewed yearning for a future where human diversity is universally recognized as a source of shared joy rather than division. Full ticketing and performance details are available through the official LSO St Luke’s website.
