Soprano Deborah Voigt takes on spectacularly difficult excerpts of Wagner's Tannhaüser andStrauss's Salome, plus Barber's Homerian monologue Andromache's Farewell for the orchestra's opening-night gala. A pair of overtures—the famous Tannhaüser opening and Barber's shimmery The School of Scandal Overture—round out the program, with Alan Gilbert on the podium.
