Not being the opera buff to appreciate recitativo secco, which abounds here, put me at a disadvantage to enjoy Orlando Finto Pazzo. Mining Vivaldi Operas for the really furious arias also left me almost empty handed. Consequently I found myself hitting the skip button on my blaupunkt through plenty of mellow passages.
Unlike the other Vivaldi Operas, this one is mostly low key. With the exception of the sinfonias, and a few arias, the music sounds much tamed and unlike what I would expect of Vivaldi.
I must say that Sonia Prina is an amazing vocal gazelle when it comes to "Andero, volero, gridero". This aria is a notch above presto, and challenging for any singer who has to musicalize the aria, and sprint on long libretto lines during short, fast, abrupt orchestrations. On my best effort, I can't even read aloud as fast as she sings.
Marianna Pizzolato sings "Scenderei per far paghi" which, lyrics aside, is the twin aria of "Gelosia" from Ottone in Villa. Interesting to me was to hear this aria without much coloratura in the melismas, and still find it quite likeable. She lifts the note in mid air, suspends it in a circling pattern, and spirals it down into anxiety. There is nothing so creative as Vivaldi's mood arias!
