A very distinctly different take on this aria. One a lyric soprano the other a dramatic soprano. Petibon is very intimate and feminine with slightly overdone English pronunciation. Flagstad is much more simple and relaxed here, allowing the music itself to shine. I prefer her diction as the more naturalistic. Flagstad has a much easier time with phrasing smoothly, her breath control and sound production steady as a rock. Petibon's is struggling a bit more trying to interject expressive details and embellishments, but it is an admirable interpretation and I hear what she is trying to do. I choose Flagstad because I prefer her perfectly polished phrasing, not simply because I love her monumental sound.
