Jerry Pournelle often reviews Los Angeles Opera productions on Chaos Manor, and while anybody is entitled to their opinion, I suspect he is one of the few science fiction writers with extensive personal experience in staging operas. So fans may be all the more interested in what he has to say about the company’s performance of The Fly:
The singers acted very well indeed, and all looked their parts. The set was imaginative and well done as was costuming. The libretto was excellent. Indeed, I liked everything about The Fly except that there was no music. There was a passable movie score for background, but the singers did their lines in recititative throughout the opera.
Pournelle also has ideas for making the score more operatic.
