Gawain and Otello are both what type of performance?
Gawain (opera) Gawain is an opera with music by Harrison Birtwistle to a libretto by David Harsent. The story is based on the Middle English romance "Sir Gawain and the Green Knight". The opera was a commission from the Royal Opera House, London, where it was first performed on 30 May 1991. Rhian Samuel has published a detailed analysis of the opera. Birtwistle revised it in 1994, and the premiere of the revised version was given at the Royal Opera House on 20 April 1994.
The Hero (opera) The Hero is a two-act opera by Italian-American composer Gian Carlo Menotti. Commissioned by the Opera Company of Philadelphia, the work premiered at the Philadelphia Academy of Music on June 1, 1976. At this point of his career, Menotti's style of composition, which rejected the avant-garde, was out of favor with the classical music world. "Time" stated in its review of the opera, "Most of Menotti's music is passable Puccini: melodic, easy to take—and totally beside the point in 1976."
