Trinity Boys Choir consists exclusively of pupils of the Trinity School in Croydon, an independent day school for boys aged 10 to 18 and sixth form girls. Fine choral singing has for many years been a distinctive feature of the school’s life and the choir has recently celebrated its fiftieth anniversary. The boys frequently appear on such prestigious stages as Glyndebourne, The Royal Opera House, English National Opera and at various opera houses abroad. The choir is especially well known for its role in Benjamin Britten's A Midsummer Night's Dream, having appeared in over 150 professional performances of the opera, on the Warner DVD, on the Virgin Classics CD and on Glyndebourne’s own label CD. Recent operatic engagements include The Royal Opera House, Glyndebourne, English National Opera, the Aix-en-Provence Festival and theatres in the USA, Belgium, China, Israel and Italy.

On the concert platform, the choir is regularly invited to perform at the BBC Proms, and was honoured to perform in Her Majesty the Queen's 80th Birthday Prom Concert at The Royal Albert Hall in 2006. The boys have performed with all the major London orchestras, and with Sir John Eliot Gardiner and his Monteverdi Choir in Spain, Germany, Italy and the UK. Trinity Boys Choir has also been invited to perform in Vienna with the Vienna Boys Choir, as well as throughout Europe and Asia.

Soloists from the choir are frequently invited to perform internationally. Recently appearances include at the Krakow Film Festival, at Amsterdam’s Concertgebouw, at the Teatro alla Scala, Milan, and in the Konzerthaus, Vienna. In 2018 Trinity soloists are performing in the UK with the Royal Ballet, English National Opera, Garsington Opera, the London Philharmonic Orchestra and the City of Birmingham Symphony Orchestra and in Germany, Lithuania, Italy, France, Malta, Holland and Spain. Having appeared in the original production and CD recording of Shell Shock, Trinity Boys Choir is delighted to be providing the soloists for its revival in Paris.
