Hymn to St Cecilia, Op.
 27 is a choral piece by Benjamin Britten (1913–1976), a setting of a poem by W. H. Auden written between 1940 and 1942.
 Auden's original title was "Three Songs for St. Cecilia's Day", and he later published the poem as "Anthem for St. Cecilia’s Day (for Benjamin Britten)".
The Habit of Art is a 2009 play by English playwright Alan Bennett, centred on a fictional meeting between W. H. Auden and Benjamin Britten while Britten is composing the opera "Death in Venice".
 It premiered on 5 November 2009 at the Lyttelton Theatre at the Royal National Theatre, with the central roles filled by Alex Jennings as Britten and Richard Griffiths as Auden (the latter replacing Michael Gambon, who had to withdraw from the production due to minor ill health).
 The performance of April 22, 2010 was broadcast to more than 200 cinemas worldwide by NTLive.
A Midsummer Night's Dream, Op.
 64, is an opera with music by Benjamin Britten and set to a libretto adapted by the composer and Peter Pears from William Shakespeare's play, "A Midsummer Night's Dream".
 It was premiered on 11 June 1960 at the Aldeburgh Festival, conducted by the composer and with set and costume designs by Carl Toms.
 Stylistically, the work is typical of Britten, with a highly individual sound-world – not strikingly dissonant or atonal, but replete with subtly atmospheric harmonies and tone painting.
 The role of Oberon was composed for the countertenor Alfred Deller.
 Atypically for Britten, the opera did not include a leading role for his partner Pears, who instead was given the comic drag role of Flute/Thisbe.
Benjamin Britten: A Life in the Twentieth Century is a book by the Australian author and composer Paul Kildea first published in January 2013 to mark the centenary year of British composer Benjamin Britten.

The Bolshoi Theatre (Russian: Большо́й теа́тр , "Bol'shoy Teatr, Big Theatre"; ] ) is a historic theatre in Moscow, Russia, designed by architect Joseph Bové, which holds ballet and opera performances.
 Before the October Revolution it was a part of the Imperial Theatres of the Russian Empire along with Maly Theatre ("Small Theatre") in Moscow and a few theatres in Saint Petersburg (Hermitage Theatre, Bolshoi (Kamenny) Theatre, later Mariinsky Theatre and others).
Anna Karenina is an opera in two acts by American composer David Carlson, based on the novel "Anna Karenina" by Leo Tolstoy, commissioned by Florida Grand Opera to celebrate the 2007 opening of the Ziff Ballet Opera House at the Adrienne Arsht Center for the Performing Arts, co-commissioned by Opera Theatre of Saint Louis.
 The libretto is by British director Colin Graham, originally contemplated for Benjamin Britten's opera commissioned by the Bolshoi Theatre (the project was cancelled by the British after the Warsaw Pact invasion of Czechoslovakia).
 Graham was to have directed the original production; after his death only weeks before the opera's opening night, the direction was taken over by Mark Streshinsky.
 The opera is in two acts with a prologue and an epilogue, lasting just over two hours.
Curlew River – A Parable for Church Performance (Op. 71) is an English music drama with music by Benjamin Britten to a libretto by William Plomer.
 The first of Britten's three 'Parables for Church Performance', the work is based on the Japanese "noh" play "Sumidagawa" (Sumida River) of Juro Motomasa] (1395–1431), which Britten saw during a visit to Japan and the Far East in early 1956.
 Beyond the "noh" source dramatic material, Britten incorporated elements of "noh" treatment of theatrical time into this composition.
 "Curlew River" marked a departure in style for the remainder of the composer's creative life, paving the way for such works as "Owen Wingrave", "Death in Venice", and the Third String Quartet.
Britten's Children is a scholarly 2006 book by John Bridcut that describes the English composer Benjamin Britten's relationship with several adolescent boys.
 Bridcut has been praised for treating such a sensitive subject in "an impeccably unsensational tone".
 The Britten-Pears Foundation described the book as having been "enthusiastically received as shedding new light on one of the most interesting aspects of Britten's life and career, in a study that is thoroughly researched, wonderfully readable and thought-provoking".
 Bridcut's book followed his television documentary "Britten's Children" shown on BBC2 in June 2004.
The Prince of the Pagodas is a ballet created for The Royal Ballet in 1957, by choreographer John Cranko, with music commissioned from Benjamin Britten.
 The ballet was later revived in a new production by Kenneth MacMillan in 1989, achieving widespread acclaim for Darcey Bussell's premiere in a principal role.
 The world premiere of Cranko's original production took place on 1 January 1957, at the Royal Opera House, Covent Garden, London, conducted by the composer.
 MacMillan's production premiering at the same venue on 7 December 1989.
