Philip Glass has surpassed Beethoven’s nine symphonies, a number that has represented a kind of psychological barrier for some composers, and he shows no signs of stopping. The National Symphony Orchestra in Washington, D.C., is set to premierehis 15th creation in the form next month.
Thursday evening in Orchestra Hall, music director Riccardo Muti and the Chicago Symphony Orchestra took on Glass’ Symphony No. 11 (2016), and the performance, though not a world premiere, was still a milestone.
