If you have a spare 19 hours one of the highlights of the Proms this year is the Staatskapelle Berlin under Daniel Barenboim rendering Wagner's Ring Cycle: 1. Das Rheingold,July 22; Die Walkure, July 23; Siegfried, July 26 & Gotterdammerung, July 28.
Two other Wagner opera will be presented as well Tristan und Isolde (7/27)and Tannhauser (8/4).
Wagner is 200 this year and a 7 month festival celebrating his works will be presented in London...wish I could attend in person. I'd gladly put up with fish and chips (heavy on the vinegar) and jellied eels if I could be present for the entire Ring cycle.
