Rupert Peacock began his professional singing career at age 8 as a treble in the world-renowned King’s College Choir in Cambridge, UK. As a child he toured internationally, sang almost daily services, and at Christmastide thrice performed the famous “Once in Royal David City” solo on television and radio for audiences of several hundred million. With King’s Choir he can be heard on recordings of the Mozart Requiem, the Fauré Requiem, choral music by Benjamin Britten, Christmas carols, and English hymn anthems.
He studied at Charterhouse School in Surrey (2014–18) with a music scholarship before serving as a Deputy Lay Clerk of Durham Cathedral. In 2024 he graduated from Princeton University with a BA in Music, a Certificate in vocal consort performance, and as the recipient of the Isidore and Helen Sacks Memorial Prize. For his senior thesis he conducted research in the archives of Ely Cathedral; the thesis presents a previously unknown piece of sixteenth-century English choral music. At Princeton Mr. Peacock sang in Decem, the University Glee Club and Chamber Choir, and the Aquinas Institute Schola Cantorum; from 2022 to 2024 he served as director of the Princeton Footnotes.
Mr. Peacock sings in Oxford Voices, Ensemble Altera, and the Saint Thomas Choir of Men and Boys in New York City.
