Giuseppe Mosca (Naples, 1772 - Messina, 1839) wrote his first opera, "Silvia e Nardone", when he was just eighteen years old. Later he composed more than forty. Some of his best known titles are: "I matrimoni liberi", "Con amore non si scherza" or "Le bestie in uomini", all premiered at La Scala.
Also premiered there, "I pretendenti delusi" is the protagonist of this post. But not with any aria from Mosca, rather an insert aria written by Rossini. It was funny, because Mosca always accused Rossini of having stolen his crescendo trademark. This is a nice aria, sung by Gregory Kunde, and the cabaletta starts at 5:40.
