Query: An indispensable performance

If you bought this recording for Anna Moffo's Nannetta alone, you would be justified. (This is Moffo at her very best -- every line beautiful, tapered, and shaded.) But the entire recording is top notch, from the conducting down to the smallest of roles. Karajan's pacing is excellent. If Schwarzkopf and Merriman lack an italianate-ness of sound (a long-stading quibble about this recording in some circles), they sing well, and the interplay among ALL the singers in this most conversational of operas is lively and specific. This recording is, quite simply, a must-have.
