The Philadelphia Orchestra and Yannick Nézet-Séguin present a program with two superb soloists. After performing the New York premiere of a new creation by Xi Wang, the orchestra showcases its principal clarinetist, Ricardo Morales, in Mozart’s indelible Clarinet Concerto. G. Mahler’s Symphony No. 4 follows. One of Mahler’s most tuneful and hopeful symphonies, the fourth remains a significant and stirring musical journey replete with expert orchestration and unforgettable moments. The fourth movement will highlight the spectacular talents of soprano Pretty Yende, who has taken the international opera world by storm.
