I will always adore the voice and performance of Victoria de los Angeles, especially when she sings Spanish song cycles. We had these boxed sets of classical music records when I was young, with two Rossini arias sung by her ("una voce poco fa" and "dunque io son'"). I sang along to them hundreds of times (I don't think my mother ever complained). Something about the timbre of her voice just made me happy. Later, I would recognize that she might not have been the most technically accomplished when compared with some other sopranos, but she was my first love.
Here's a charming interview clip, with a song performance, from British TV.
Best comment on this clip ("Che gelida manina" with the divine Jussi Bjorling): her singing was "la dulzura al servicio del canto."
