(Spohr's Alruna, Queen of the Owls if it were really inexpensive, just to have the title. One of the numbers is available as a clarinet&piano duo)
It is indeed an extraordinary title! I like Spohr's music (he was completely overlooked last year among the Big Boy anniversaries) but I've never heard this at all, and had no idea it existed.

As mentioned on another thread, I rate this short (single-cd) opera very highly. It has some stupendous music in it. The opening is audacious... a spa-town waltz that emerges quickly out of a whirling chaos of strings. I'm sure Handel would have approved - it's an opera in which someone really
does push the soprano out of the window!

The sudden leaps in chronology in the plot would make it ideal material for a "filmed for dvd" production - Doubek has to age about 14 years between the end of the first act, and the end of the opera. It's one of the few operas I can think of in which the cast are rehearsing a
different opera on-stage during the action

The Gerd Albrecht recording is very good, but has some hideous singing from "Mila's mother", which might be intended to sound "drunken and deranged" as the character is - but actually just sounds awful

There's a Mackerras recording with WNO, but sung in English in the "Peter Moores" series.
