I have a LP of this album. In writing this review I have to assume the quality of this CD is not an issue and all the discussions here are just directed at the music. Lorengar was a Spanish and based in Berlin. Like other well known singers she sang all over the world, at the Met, Vienna, everywhere else, and as a regular in San Francisco. But I got to agree with the review before me saying that Lorengar is not a household name (in the US) and that she did not received the recognition she should have deserved. By my guess, the problem being that quite often there is a miss conception that the so call diva is traditionally a lyric spinto whose fame was built on a set of standard Italian repertoire, on Puccini so to speak. A great Wagnerian soprano also is considered by some as diva. Lorengar was neither type of these. Though, she mastered all those, Puccini, Verdi, and the lighter Wagner, and performed them in all the big houses; and nonetheless she did have a very distinguished career. Her voice is unique. If you like a crystal clear voice this album is for you. Even if you don't particularly care for a crystal clear voice this album still is for you. This album contents a very good sampler of opera (and operetta) arias of the Viennese tradition. The duet that she sang together with Arleen Auger is not going to be missed. I am sure you will enjoy it as I do.
