Since the founding of a mixed voice choir in 1972, the Choir of Clare College has gained an international reputation as one of the world’s leading university choirs. In addition to its primary function of leading services three times a week in the College chapel, the Choir keeps an active schedule recording, broadcasting, and performing. Former directors have included John Rutter and Timothy Brown. Under the direction of Graham Ross, Director of Music since 2010, it has been praised for its consistently ‘thrilling’ and ‘outstanding’ performances worldwide. Recent engagements include performances with the Orchestra of the Age of the Enlightenment, London Philharmonic Orchestra, Britten Sinfonia, Aalborg Symphony Orchestra, Malaysian Philharmonic Orchestra and Orquesta Sinfonia Nacional de Mexico, as well as recitals in Barcelona's Palau de Musica, El Escorial Madrid, Palacio de Bellas Artes Mexico City, St John's Smith Square London, and across the USA and Canada.

In addition to live performances, the Choir has produced an impressive discography of more than forty recordings. Their recordings under Graham Ross on the Harmonia Mundi label have been released to great critical acclaim, earning praise for ‘exceptional singing’ and ‘immaculate performances’, a Le Choix de France Musique and a Diapason d’Or award, and garnering a Gramophone Award nomination. The Choir’s nine-disc series of Music for the Church Year has received numerous 5 star reviews in the national and international press, with recordings for Advent (2013), Passiontide (2014), Christmas (2014), Ascensiontide and Pentecost (2015), All Saints and All Souls (2015), Easter (2016), Epiphany (2017), Corpus Christi (2017) and Trinity (2018).
