Last night’s concert of the @[100043116381457:2048:Princeton Symphony Orchestra] was a triumph, with possibly the best “Knoxville: Summer of 1915” I have ever heard. Congratulations to the PSO for securing Angel Blue on such short notice. (Pretty Yende, the scheduled artist, was forced to cancel due to illness.) The “encore,” for which Blue invited a voice student from the audience to join her in Puccini’s “O mio babbino caro,” was a masterstroke. Yasmine Swanson rose to the occasion, sending the audience into the night with smiles on their faces. The concert will be repeated this afternoon at 4:00 at Princeton’s Richardson Auditorium.
