Nicholas began his musical career as a chorister at Salisbury Cathedral, and then from Uppingham School to King's College Cambridge where he sang as a choral scholar. Moving to London in 1995, he quickly found himself immersed in an international choral scene, performing, touring and recording widely with groups such as Polyphony, The King’s Consort, The Sixteen and The Cardinall’s Musick. In 1997, he began singing and recording with The Huelgas Ensemble, performing all over Europe as a consort singer and soloist. Poliziano’s Orfeo was one of his most prominent roles, which he performed on Dutch national radio.
In 2000, Nicholas joined The Tallis Scholars as a regular member, recording and performing regularly in the United States, the Far East and all over Europe. This also coincided with his first venture into singing teaching, and in 2008, he joined music department of The King’s School Canterbury, where he is now Head of Singing.
Nicholas continues to work with a select group of vocal ensembles such as Alamire, The Cardinall’s Musick and Tenebrae. Many of his recordings have won awards, most notably his recording of choral works by Benjamin Britten with Polyphony in 2003 (Gramophone Award) and works by Victoria with Tenebrae in 2011 (BBC Music Magazine awards, Best Choral Disc).
