David Morneau is a composer, producer, and trombonist. In 2016, he joined forces with composer-producer Melissa Grey, establishing a “wholly original” and “inventive” practice. Their work has received the following acclaim: “production is masterfully realized and consistently creative,” “beautiful and transcendent,” “hypnotic allure,” “a masterclass on how to utilize space,” “a masterpiece,” “a completely unique sonic world,” and “shows technical mastery… exudes fun… imaginative.”

Grey & Morneau recently released Always Becoming (2023), a collaborative composition with Robert Kirkbride (current spokesperson, founding trustee for PreservationWorks; former Dean, Parsons School of Constructed Environments). In 2022, they designed a soundscape for the exhibition space for The Empty S(h)elf, a project by the artist-curator Angela Grauerholz, in collaboration with designer Réjean Myette, at Occurrence – Space in Montreal. Grey & Morneau were awarded the 2018 Joan C. Edwards Distinguished Professors of the Arts, College of Arts and Media, School of Music, Marshall University in West Virginia, and were the subjects of the documentary Ao Vivo no Casarão | Lado B by Cristina Gagnebin Müller & Yuri Pires Tavares. Other commissions include: Photon Ecstasy (2016), with artist Dan Rose, featured at the Kislak Center for Special Collections, Rare Books and Manuscripts, University of Pennsylvania Libraries, Philadelphia, PA, and mem mer mère (2019) with cellist Kate Dillingham at the Cultural Center at the Havre de Grace Opera House, Maryland.

In addition to their production and composition practice, Grey & Morneau, since 2014, have jointly curated and produced numerous concert events, including Soft Series, a concert series dedicated to presenting soft premieres and introducing new audiences to new music. This series was live-streamed from Clocktower Radio (“one of the first all-art online museum radio stations in the world”).

Morneau’s Not Less Than the Good, a commission from New Thread Quartet, was an expansive reflection on Henry David Thoreau’s Walden that features sounds recorded during the pre-dawn and early morning hours at Walden Pond and readings performed by poet J. D. McClatchy. Not Less Than the Good was premiered at The Morgan Library & Museum in New York to open the exhibition This Ever New Self: Thoreau and His Journal.

Morneau's Love Songs is a collaboration with ten poets combining Shakespeare's sonnets with contemporary poetry in genre-crossing songs (2013). He followed up with the release of Love Songs Remixed (2015), which enlisted 9 other composers and producers to create new music using the existing songs, expanding the idea of what a remix can be.

With Vintage Machines, Morneau is creating a series of pieces utilizing vintage video game systems to make music. Morneau explores beyond the impulse toward nostalgia, embracing the limitations of the Nintendo Game Boy in the pursuit of self-expression. Music includes Abandoned Revolution, a performance collaboration with choreographer Boris Willis; in8 an 8-channel deconstruction of Game Boy loops; Another Dimension, a bustling meditation that stretches beyond 50 minutes (featured on Hans Tammen’s Dark Circuits series); and Broken Memory, an album for Immigrant Breast Nest that "absolutely wrecks shop.… For that, David Morneau wins."

Morneau’s 60x365, a yearlong musical project for which he composed a new one-minute composition every day, was featured on NPR’s All Things Considered with Robert Siegel.

Morneau lives and works in New York.
