This just in from the Met press office: “Giovanni Meoni will sing the role of Ezio in Verdi’s Attila on February 27, March 3, 6, 9, 12, 15, and 19, replacing Carlos Alvarez, who is ill.” (Photo: Ken Howard/Metropolitan Opera)

UPDATED: Note the correction above, i.e., Meoni is currently announced only for the performances to be conducted by Riccardo Muti; “TBA” is on for the three evenings to be conducted by Fabio Marco Armiliato. (That will change soon enough, sadly.)
