Three of Beethoven’s seismic symphonies are featured on the Chicago Symphony Orchestra’s Ravinia residency this summer, and Alsop heads up the pack on July 14 with the world-moving Ninth, featuring the Chicago Symphony Chorus and soloists soprano Tamara Wilson, mezzo-soprano Michelle DeYoung, tenor Paul Appleby, and bass-baritone Ryan Speedo Green. Gustavo Dudamel makes his eagerly awaited debut leading the Seventh on July 18 with an all-Beethoven program that also features his longtime, equally starry collaborator Yuja Wang performing the First Piano Concerto. Last, but not least, of Ravinia’s triptych is the Fifth, fated to be feted in the hands of Vasily Petrenko on August 4.
