As you may have already heard, Karita will sing the first act of Die Walküre in Musiikkitalo, Helsinki. Unfortunately the 2 concerts are part of the series, which means the tickets are already more or less sold, especially when it comes to better seats.
Yes, I read about the concerts with the RSO in Helsinki next September. Pity that both concerts belong to a subscription series making it difficult to get decent seats. It's, of course, the selling policy of the RSO subscriptions...
