This 1973 Glyndebourne performance of Le Nozze di Figaro is, in my humble opinion, one of the best "traditional" productions. Video and sound quality are not awesome, and I didn't think I would particularly enjoy Ileana Cortrubas as Susanna.
But I learned to overlook the quality issues (and everyone making clomping noises on the raked stage), and Cortrubas is great as Susanna. This performance also captures pre-royal-wedding Kiri Te Kanawa, and Frederica von Stade in her signature role of Cherubino (not included in this clip.)
Note how the Countess suddenly turns apprehensive on the final "il capirar," as if she is thinking, "OMG, what are we getting ourselves into?"
Susanna & Rosina, plotting again.
