I've been looking for a good Il Trovatore DVD for a while. I find everything about the 1988 Met production to be perfect except for Eva Marton as Leonora, and she so badly ruins the whole show for me that that mis-casting alone forced me to go seek other DVDs.
I just watched the Karajan/Vienna State Opera (1978), and enjoyed it, but the orchestra just doesn't have the fire and precision that the Met does. And there are lots of problems with togetherness between singers and orchestra.
If there is a DVD out there that has an orchestra that plays with the fiery clarity and precision of the Met orchestra, in perfect synchronization with the singers, but without a mis-cast Leonora, I'd love to learn of it!
