William Brittelle is a Brooklyn-based, Grammy-winning producer and composer, producer and creator of hyper-text and multimedia. An avid collaborator, Brittelle has worked with a number of artists across multiple disciplines, including Roomful of Teeth, Justin Vernon (Bon Iver), Bryce Dessner (The National), Son Lux, Oneohtrix Point Never, Enongo Lumumba-Kasongo (Sammus), Aditya Prakash, Shahzad Ismaily, Duran Duran, Wye Oak, David Longstreth (Dirty Projectors), Kanye West, and the Seattle, Baltimore, Indianapolis, and North Carolina Symphony Orchestras, the Basel Sinfonietta, and the Los Angeles Philharmonic. His most recent full-length LP entitled Spiritual America featuring Wye Oak, the Metropolis Ensemble, and the Brooklyn Youth Chorus, was released by Nonesuch/New Amsterdam in 2019. His prior albums were profiled on NPR's All Things Considered and in the New York Times, Los Angeles Times, MUSO, The Nation, and The New Yorker.

Brittelle's work has been presented at venues across the world, including the Hollywood Bowl in Los Angeles, Lincoln Center, the Kennedy Center, Teatro Colón in Buenos Aires, the Metropolitan Museum of Art, Da Camera in Houston, Seattle's Town Hall, and the Ecstatic Music Festival in New York. Post-pandemic, his work has focused increasingly on complex collaborative networks of interlinked text and multimedia, a trend culminating in the launch of Eternal September, a vast digital alternate reality artistic platform being developed with the support of the Brown Arts Institute.

Increasingly active as a producer, upcoming and recent projects include albums with Alex Temple/Julia Holter/Spektral Quartet, Metropolis Ensemble/Wye Oak, composer Missy Mazzoli, vocalist/percussionist Jodie Landau, the string ensemble Owls, singer/composer Aditya Prakash, movement and voice ensemble Constellation Chor, and keyboardist Erika Dohi. Roomful of Teeth's 2023 album Rough Magic garnered Brittelle a Grammy award as producer (BEST SMALL ENSEMBLE PERFORMANCE) and a Grammy nomination as composer (BEST CONTEMPORARY CLASSICAL COMPOSITION). Along with composers Judd Greenstein and Sarah Kirkland Snider, Brittelle is the co-founder and co-artistic director of New Amsterdam Records and serves as house producer for Shahzad Ismaily’s Figureight Recordings in Brooklyn.
