He is the Director of Music at the University of Warwick. Sir William Turner Walton, OM (29 March 19028 March 1983) was an English composer.  During a sixty-year career, he wrote music in several classical genres and styles, from film scores to opera.  His best-known works include "Façade", the cantata "Belshazzar's Feast", the Viola Concerto and the First Symphony. A Night at the Chinese Opera is an opera in three acts by Judith Weir, who also wrote the libretto.  Aside from an earlier opera for children, this was Weir's first full-scale opera, written on commission from the BBC for performance by Kent Opera.  Weir incorporated an early Chinese play of the Yuan dynasty, "The Orphan of Zhao", as the centrepiece of Act 2 of her opera. Blond Eckbert is an opera by Scottish composer Judith Weir.  The composer wrote the English-language libretto herself, basing it on the cryptic supernatural short story "Der blonde Eckbert" by the German Romantic writer Ludwig Tieck.  Weir completed the original two act version of the opera in 1993, making "Blond Eckbert" her third full-length work in the genre.  Like its predecessors, it was received well by the critics.  She later produced a one act "pocket" version of the work.  This uses chamber forces rather than the full orchestra of the two act version and omits the chorus.  The pocket version receives frequent performances, especially in Germany and Austria, while the full version is available in a recording featuring the original cast.
