There is a range of musical opportunities with a symphony orchestra, brass and string ensembles, a junior choir, a choral society (known in the school as "Christmas Choir") and a barbershop group. Recent choral performances have included "Belshazzar's Feast" (Walton), the Requiems of Mozart, Verdi and Fauré, and "Gloria" by Poulenc. The Brentwood School Big Band, which is now in its 34th year, often performs concerts for charity outside school and tours European every other year. The Big Band has released a number of albums, most recently "Music to Drive By" in 2013. In 2008, the year of Brentwood School's 450th Anniversary, the school took part in a service in St Paul's Cathedral, in which the choir performed various English choral works. In the same year, a cantata "The Old Red Wall", composed by the former Director of Music David Pickthall, was premiered at the 450th Anniversary Festival at the "Brentwood Centre". The cantata was based on the school song "The Old Red Wall" and featured new text by David Dunn.
