In 2012, the Late Stan Mears published in the British Music Society Journal a brief review of British Operas composed during the reign of Elizabeth 11. There were 147 mentioned. I could have added a few more. My question to the members of this forum is: are any British operas composed during this period the kind that can be recommended to this forum ? The only possibility that I could spot was Wilfred Joseph's Rebecca from 1983.
Needless to say most of them have disappeared without trace.
Needless to say most operas of every period have disappeared without trace. It says nothing about the period. Britten's, for all that we can't discuss them here, have done pretty well, even several of his post-1951 ones; Tippett''s too. Will see if I can find an answer to your question though...
There's also Williams' The Parlour (1961) but that -has- disappeared I agree...
Sorry - this is all well outside our remit.
