I have just seen a ROH website announcing wonderful news. In March (24, 27, 30) and April (3, 6, 9), Madame Mattila will be singing the role of Kostelnicka, and on May 29th and in June (2nd, 8th, 12th, 15th, and 18th)she will be singing Klytemnastra. After her stunning Prioress in Le Dialogue des Carmelites it is a great joy to think of the what we have to look forward to.
