La Cieca is suffering a mild case of Empty Nest Syndrome this afternoon, since she just found out that parterre.com fave Stephen Costello is all grown up. It turns out that Stephen is the “TBA” who will sing Edgardo (his very first!) in Lucia di Lammermoor at the Met on October 25. In this spectacular followup to his scheduled house debut as Arturo next week, Stephen is joined by Annick Massis, Mariusz Kwiecien and John Relyea in a performance conducted by James Levine and broadcast live on Sirius.

In other TBAlicious news, an artistic administrator or two is breathing a little easier this afternoon as the Met has finally announced completed casting for their new production of Verdi’s Macbeth — only a month before the October 22 opening! Maria Guleghina will sing Lady Macbeth in the “Live in HD” January 12 matinee performance relayed to movie theaters around the world. She will also sing the role on January 9 (which had not been previously announced) and on October 22, 26, 31, and November 3 as scheduled. Andrea Gruber will sing the role of Lady Macbeth on January 5 and 15 (which also had not been announced) as well as on the previously scheduled dates of May 9, 13, and 17. The new production of Macbeth is directed by Adrian Noble.
