I see a couple of the opera overtures have had recordings too - either I haven't heard them, or I have, but they didn't 'stick with me'. I'll need to give them a listen!
I don't think that's the entire opera - there's a complete vocal score on IMSLP...
The
Drottningen av Golconda overture is lovely - some rather William Tell-ish divisi celli at the start and a second subject starting with a leap of a 9th which once heard (by me, anyway) has never been forgotten. And good detective work matching score of
Estrella to recording - I did wonder how Act 3, from the synopsis given on Wikipedia involving storms at sea, escapes, curses, rescues and suicides, could all fit into 18 minutes.
And the same Wikipedia article mentions a CD of extended excerpts - that'll be it, then.
