According to the October issue of Opera (the British opera magazine), Karita will be singing Katya Kabanova at the Chicago Lyric Opera from November 2009 on. No exact performance dates were given.
By the way, Karita's latest Salome at the Met was the most striking triumph she has achieved so far both vocally and artistically on stage. Just awesome! Saw her live on the last performance, Sat October 16th.
