From what I remember, her intonation was off on a few notes, and her tone wasn’t what I thought an opera singer should sound like, but what do I know.
Too drawn out and, IMO, the “operatic diva” took occaision to embellish.
The Anthem should be presented as written and not used as a vehicle for advertising one’s singing ability and/or voice range.
What she did in 5 minutes shoud have been over-and-done-with in 3.5. Color me unimpressed.
