Mead was born in Chelmsford, Essex, U.K., in 1981. As with so many other early music performers, he had his first musical training as a treble chorister at Chelmsford Cathedral. He entered the junior program at Trinity College of Music, studying cello and piano, and went on to King's College, Cambridge, as a choral scholar and musicology student. For graduate studies, he won scholarships to attend the Royal College of Music and study with countertenor Robin Blaze. During his last year, he made his operatic debut in the difficult role of Ottone in Monteverdi's L'incoronazione di Poppea at France's Lyon Opera under William Christie. Mead has sung that role several times but has specialized in the operas and choral music of Handel. Major exposure in Britain came at the BBC Proms in 2004, where he performed in Biber's Missa Bruxellensis with the Academy of Ancient Music, and in a celebrated 2006 production of Giulio Cesare, where Mead sang the title role under conductor Emmanuelle Haïm, substituting for an ill David Daniels. In 2004, Mead was heard on recordings for the first time in a pair of albums; one, Caro Amor, featured Baroque music, while the other, Ned Rorem: On an Echoing Road, was of a 20th century work.
Mead has performed the monuments of Baroque choral repertory not only with major early music groups but with conventional symphony orchestras, singing Handel's Messiah with the New York Philharmonic. In the 2010s, he broadened his repertory, appearing in several early Mozart operas with Britain's Classical Opera Company and in Philip Glass' Akhnaten with the Vlaamse Opera in Belgium. The Prince Consort, of which Mead is a founding member, has performed works by Brahms, Ned Rorem, and Stephen Hough. In addition to numerous recorded appearances as part of ensembles, Mead has released several solo recordings, including Purcell: Songs and Dances, on the Alpha label in 2018. In 2020, he was heard on a recording of Handel's Messiah, HWV 56, with the Akademie für Alte Musik, Berlin, and he returned in 2022 as part of the cast in Handel's opera Amadigi di Gaula, HWV 11, with the Early Opera Company. ~ James Manheim, Rovi
