Maury tipped me to the rumor on the internets that 23-year-old Lisette Oropesa may be replacing Isabel Bayrakdarian (as Susanna) in the Met's October Figaros.
Anyone who's heard Oropesa at the 2005 Met Council Finals or in her recitals and bit parts (where, incidentally, her sound has easily filled the Met) since knows she is a remarkable singer of rare charm and early artistic maturity. (She continues to develop and learn her vocal instrument, but her sense of phrase, word, and manner is already whole.)
If Gelb doesn't try to throw in a "name" at the last minute, the Figaros that seemed superfluous without Dorothea Röschmann may again be a must-see.
UPDATE (9/29): It's official. Oropesa sings Susanna next Tuesday and Saturday, while the legendary "TBA" takes the rest of Bayrakdarian's October dates here.
