Query: A beautiful video of a beautiful production!

I have been familiar with Herbert von Karajan and the singers on this DVD for a long time before finally seeing them in action, and I must say, not one of them failed to impress, and each one of them is just as amazing as I had always expected. This is absolutely one of the greatest productions of Don Giovanni, which just happens to be my favorite opera, in this whole world. Von Karajan seems to be still at the peak of his power with the baton, and I just cannot say enough great things about the cast, especially Anna Tomowa-Sintow, Samuel Ramey, Julia Varady, and Kathleen Battle. This is a must-have in the collection of any opera/Don Giovanni lover!
