To my ears, this is the best recording of Le Nozze di Figaro.
Boehm's pacing is, as ever in Mozart, immaculate.
Prey as Figaro is ideally weighty and not too funny(why should Figaro be funny with his suspicions?), Fischer-Dieskau is as refined as one would expect but he's also scheming and villainous and the two tenors are excellent in their roles.
The Marzelline sounds just the right age - not an old matron or a young girl - and has the perfect degree of hardness in the voice. Mathis' Susanna is charming, witty and romantic and Troyanos is passionate and confused as Cherubino.
The star here, though, is definitely Janowitz as the Contessa - her voice is so beautiful (and ideal for Mozart and Richard Strauss) it defies description but she is also dramatic and moving.
All arias are included (a rarity) and are sung by the appropriate singers (not so on some earlier sets) and, though this is a recording from the 60's, the sound is great.
