Fritz Wunderlich is one of those singers whose voice, while you are listening to it, seems to eclipse all others. Ravishingly beautiful, perfectly produced, radiant, even, mellow, it flows out with effortless ease like a golden stream. His breath is endless, and there is nothing that he cannot do. On these two very generous discs he sings arias ranging from Handel to Viennese operettas and sounds equally at home in all of them, vocally and stylistically. Mozart was one of his specialties, and the five arias opening the program have a beguiling, caressing lyricism that melts the heart. The selection includes familiar arias by Wagner, Tchaikovsky, Massenet, Donizetti, Smetana (including a duet with Pilar Lorengar), as well as several by composers whose operas were popular in the 1960s, when the records were made, but have now fallen into oblivion, such as Lortzing, Flotow, Cornelius, Kienzl, Nicolai, Thomas, Boieledieu. Wunderlich sings them all with the same seriousness and commitment, making the lesser ones sound better than they are, and creating real characters with color, nuance and expression. In keeping with the European tradition of performing opera in the local language, he sings everything in German, except the famous "Ombra mai fu" from Handel's Serse, which must have escaped the translators. Choosing from the best operettas by Lehár, Johann Strauss, Millöcker, Kálmán and Fall, he captures their smiling, tongue-in-cheek lightness and never lets the catchy tunes become corny or sentimental. (Listen also to his two very different, but equally wonderful recordings of Mahler's Song of the Earth under Schmidt-Isserstedt on BellaVoce and Klemperer.) In 1966, aged 36, at the peak of his artistry and his career, Wunderlich died after a fall, a month before he was to make his debut at the Metropolitan Opera. --Edith Eisler
