Dear Meche Kroop, thank you for the excellent review.
"The zarzuela they chose, , was composed by Gerónimo Giménez and Manuel Nieto with a libretto by Guillermo Perrin and Miguel de Palacios; it premiered in Madrid in 1901 and is best known for the soprano aria "Me llaman la primorosa" which we have heard the marvelous Maria Brea sing in recital. How totally excellent it was to hear her sing the entire role of Elena, a wannabe diva who defies her strict father Nicolás (portrayed by baritone Stan Lacy) to star as Rosina in Rossini's masterpiece Il barbiere di Siviglia in a regional company in Burgos.
This gave Ms. Brea an opportunity not only to sing the afore-mentioned "Polonesa" as an interpolation for the voice lesson scene, but to also let out all the stops for "Una voce poco fa". Of course we have heard sopranos sing this mezzo role before, but we were particularly taken by Ms. Brea's ability to handle the lower register as well as committing to the firework coloratura of the cabaletta."
