When this CD was first released, I happened to hear the track with "Una voce poco fa" played on a classical-music radio station. For over 50 years I had been a devoted "fan" of instrumental classical music, but, in just 3 minutes, Kasarova's performance expanded and altered my mind and heart. When I attempted to purchase an audio tape of her singing, I discovered none was for sale anywhere. My solution? Buy the CD--and THEN buy a CD player. Five or six years later, I own over 1800 CDs, about 2/3 of them operatic music. My preferences are now mainly for bel canto singers who are mezzos or contraltos. Rossini, Handel, and Bellini are my favorite composers. Why? Chiefly because of my chance encounter with Ms. Kasarova's wonderfully flexible, rich, warm voice. She caused me to get season tickets to the Met for the past four years (where I was finally able to hear/see her in THE BARBER OF SEVILLE--the best of the four performances I've attended). For purposes of easy comparison, I have "imported" tracks from this CD onto my computer's hard drive along with those of several dozen other mezzos singing the same arias. After many hours of back-to-back listening, in almost all cases I greatly prefer the versions of Kasarova. This CD is an excellent "starter" purchase for any beginners who wish to explore what opera has to offer. For "experienced" listeners, it is a must-have!
