"Ax and Barton began Thursday's concert with four songs written by Schubert based on the poetry of Johann Wolfgang von Goethe, including Goethe's greatest work, "Faust." Each song has its own, distinct style. And in each case, Ax and Barton beautifully brought each work to life. Listening to the four songs, I was especially in awe of the range and power of Barton's voice. Soft and soulful in "Schafers Klagelied," strong and firm in "Gretchen am Spinnrade," Barton can do it all and made everything sound so simple."
–Ken Ross, Mass Live
“Ten years out of the Tanglewood Music Center, Barton returned firmly established as a leading lady of the opera world. There was something operatic, too, in her singing of the four Schubert songs, all to poems by Goethe."
