Cecilia has announced the schedule for next year's Whitsun festival here. There is mention of Cecilia Bartoli singing "Wir hab nun Trauerigkeit" from the Deutsches Requiem, her first appearance that I know of in German. She sang Ravel in Yiddish, but that doesn't count. Pape will also sing and Barenboim conduct.
This goes with Norma. Ach. I think we should expect the recording to be out by then.
There will be a piece by Sofia Gubaidulina. Gergiev will conduct more than one program. Maybe I'll feel better by then.
