Levine also is slated to conduct revivals of Rossini’s “L’Italiana in Algeria (The Italian Girl in Algiers),” Verdi’s “Nabucco” with Placido Domingo in the title role and Mozart’s “Idomeneo.” Levine is to lead Strauss’ “Der Rosenkavalier” starting April 13, 2017, in a Robert Carsen staging that appears to be Renee Fleming’s farewell to staged performances of the core opera repertoire. Gelb wouldn’t say whether he has spoken with possible successors. “It’s really going to be a question of how rehearsals go,” Gelb said Monday. Levine is scheduled to conduct revivals of Verdi’s “Simon Boccanegra” starting April 1 and Mozart’s “Die Entfuehrung aus dem Serail (The Abduction from the Seraglio)” beginning April 22.

His baton technique was erratic during performances of “Tannhaeuser” and “Die Fledermaus” this season, and Levine withdrew from a new staging of “Lulu.” Gelb said the Met was prepared to announce Levine’s retirement as music director a few weeks ago, effective at the end of this season, but was awaiting word whether a medication change would lead to improvement. He was sidelined for two years with a spinal injury and before he returned in 2013, conducting from a motorized wheelchair, the Met said he was being treated for a Parkinson’s disease-related disorder. Levine, who turns 73 in June, has been the Met’s leading force since his debut in 1971 and has been music director or artistic director since 1976. “Ultimately, his ability to conduct next season will be determined by how he is physically, and it’s too soon to say,” Met general manager Peter Gelb said in an interview timed for the company’s announcement Wednesday of its 2016-17 schedule. Whether he actually appears remains uncertain. James Levine is scheduled to conduct 31 performances of four productions at the Metropolitan Opera next season.
