Diana Damrau being as camp as pink ink! singing Glitter and be gay. Acting! And doing the 'full aspirated h' on the ha-ha chorus!
She also did a fair turn as the Queen of the Night ... She has three arias, and all three from this particular production were uploaded. You can find them (and others) in the Related Videos side-bar.
One of the comments on this, the "fancy show off" second aria, talks about the non-musical reasoning of the book - that this is the Queen of the Night enchanting Pamina into doing her will, cajoling, demanding, ordering, and finally using magic to coerce her.
Natalie Dessay also did it well, though she seems more to be bullying the girl into obedience. Remarkable for her being pregnant while doing this performance, which (according to the comments) was also true of Josepha Hofer, Mozart's sister-in-law and the person for whom the role was written.
By comparison, Luciana Serra did the same part and I don't think that production understood the book as well. Pamina doesn't seem to have the same sense of torn-between-dutiful-love-and-loathing-o
And since someone asked at one point whether an ordinary singer can sing opera, and based on my conversations with maus_merryjest some years ago, they can but it'll probably suck and it'll probably hurt their voice because they've learned bad habits...
Florence Foster Jenkins was a wealthy socialite and benefactor of the arts in the first half of the 20th century. She recorded her renditions of classical vocal works to give as gifts to friends. Here she sings Mozart's aria "Queen of the Night". Beware. This is an historical artifact, but not really a great performance. This is an extreme amateur trying things far beyond her skill and range, and it's admirable but painful at the same time.
OK, so Patrizia - an italian/canadian rock singer - did a rock version. She learned to sing rock and roll first, then learned opera, per her bio on her webbage. Also the video is creepy and bizarre.
Geez, everybody and their cockatiel has covered this, but other than children, socialites, and opera-trained people I cannot find a copy of this on YouTube that's by a regular ordinary singer. Probably a clue.
Well, there was ONE by a person who is studying operatic singing ... here ... and she explains that it's a very hard role, and that she may not be able to handle it.
