This is an interesting interpretation and I am not disputing this ensemble's scholarship, but the piece is unusual because it shifts back and forth between the plagal Mixolydian mode and the authentic Dorian mode. Both modes cover the same territory, although the finalis of each mode is different. It is a bit of a jolt to hear her singing a b flat in a Mixolydian passage, but I can understand why she does it. If they are interpreting it as a Dorian passage the rule of 'una nota super la semper est canendum fa' would be in play. My opinion, however, is that those passages are in the hard hexachord and that a b flat would not be warranted. This ensemble's musicianship, however, is not in question. They are a superior ensemble and they play beautifully.
Beautiful. Formidaly beautiful.
C est très beau ❤️
