Are, A Village Romeo and Juliet and Einstein on the Beach both operas ?
A Village Romeo and Juliet A Village Romeo and Juliet is an opera by Frederick Delius, the fourth of six operas. The composer himself, with his wife Jelka, wrote the English-language libretto based on the short story "Romeo und Julia auf dem Dorfe" by the Swiss author Gottfried Keller. The first performance was at the Komische Oper Berlin on 21 February 1907, as Romeo und Julia auf dem Dorfe. Thomas Beecham conducted the British premiere at the Royal Opera House, Covent Garden in London on 22 February 1910. The US premiere was on 26 April 1972 in Washington, D.C.
Un re in ascolto Un re in ascolto ("A King Listens") is an opera by Luciano Berio, who also wrote the Italian libretto. It is based on a short story, Under the Jaguar Sun by Italo Calvino, but incorporates excerpts from Friedrich Einsiedel's 1778 libretto (as reworked by Friedrich Wilhelm Gotter between 1790 and 1791) for an opera based on Shakespeare's "The Tempest". This became "Die Geisterinsel" in 1798, set to music written by Friedrich Fleischmann. In addition, W. H. Auden's "The Sea and the Mirror: A Commentary on Shakespeare's The Tempest" was a source.
