As the Metropolitan Opera prepares for the opening night of Strauss's Capriccio this evening, with Renée Fleming taking on the role of Gräfin Madeleine, we look back over the last 69 years since the premiere of the "conversation piece for music" and see who have been favorites to play the leading lady either on the opera stage, in concert performance or in the recording studio. Check out the list after the jump and don't forget to listen to the broadcast of the Capriccio premiere live from the Metropolitan Opera on Sirius XM Radio tonight at 8PM EST.
